### Definition and Purpose
Block diagrams are an intuitive and efficient way to represent complex systems, processes, or architectures visually. They are composed of blocks and connectors, where blocks represent the fundamental components or functions, and connectors show the relationship or flow between these components. This method of diagramming is essential in various fields such as engineering, software development, and process management.
The primary purpose of block diagrams is to provide a high-level view of a system, allowing for easy understanding and analysis without delving into the intricate details of each component. This makes them particularly useful for simplifying complex systems and for explaining the overall structure and interaction of components within a system.
Many people use mermaid flowcharts for this purpose. A side-effect of this is that the automatic layout sometimes move shapes to positions that the diagram maker does not want. Block diagrams use a different approach. In this diagram we give the author full control over where the shapes are positioned.
### General Use Cases
Block diagrams have a wide range of applications across various industries and disciplines. Some of the key use cases include:
- **Software Architecture**: In software development, block diagrams can be used to illustrate the architecture of a software application. This includes showing how different modules or services interact, data flow, and high-level component interaction.
- **Network Diagrams**: Block diagrams are ideal for representing network architectures in IT and telecommunications. They can depict how different network devices and services are interconnected, including routers, switches, firewalls, and the flow of data across the network.
- **Process Flowcharts**: In business and manufacturing, block diagrams can be employed to create process flowcharts. These flowcharts represent various stages of a business or manufacturing process, helping to visualize the sequence of steps, decision points, and the flow of control.
- **Electrical Systems**: Engineers use block diagrams to represent electrical systems and circuitry. They can illustrate the high-level structure of an electrical system, the interaction between different electrical components, and the flow of electrical currents.
- **Educational Purposes**: Block diagrams are also extensively used in educational materials to explain complex concepts and systems in a simplified manner. They help in breaking down and visualizing scientific theories, engineering principles, and technological systems.
These examples demonstrate the versatility of block diagrams in providing clear and concise representations of complex systems. Their simplicity and clarity make them a valuable tool for professionals across various fields to communicate complex ideas effectively.
In the following sections, we will delve into the specifics of creating and manipulating block diagrams using Mermaid, covering everything from basic syntax to advanced configurations and styling.
Creating block diagrams with Mermaid is straightforward and accessible. This section introduces the basic syntax and structure needed to start building simple diagrams. Understanding these foundational concepts is key to efficiently utilizing Mermaid for more complex diagramming tasks.
### Simple Block Diagrams
#### Basic Structure
At its core, a block diagram consists of blocks representing different entities or components. In Mermaid, these blocks are easily created using simple text labels. The most basic form of a block diagram can be a series of blocks without any connectors.
**Example - Simple Block Diagram**:
To create a simple block diagram with three blocks labeled 'a', 'b', and 'c', the syntax is as follows:
```mermaid-example
block-beta
a b c
```
```mermaid
block-beta
a b c
```
This example will produce a horizontal sequence of three blocks. Each block is automatically spaced and aligned for optimal readability.
### Defining the number of columns to use
#### Column Usage
While simple block diagrams are linear and straightforward, more complex systems may require a structured layout. Mermaid allows for the organization of blocks into multiple columns, facilitating the creation of more intricate and detailed diagrams.
**Example - Multi-Column Diagram:**
In scenarios where you need to distribute blocks across multiple columns, you can specify the number of columns and arrange the blocks accordingly. Here's how to create a block diagram with three columns and four blocks, where the fourth block appears in a second row:
```mermaid-example
block-beta
columns 3
a b c d
```
```mermaid
block-beta
columns 3
a b c d
```
This syntax instructs Mermaid to arrange the blocks 'a', 'b', 'c', and 'd' across three columns, wrapping to the next row as needed. This feature is particularly useful for representing layered or multi-tiered systems, such as network layers or hierarchical structures.
These basic building blocks of Mermaid's block diagrams provide a foundation for more complex diagramming. The simplicity of the syntax allows for quick creation and iteration of diagrams, making it an efficient tool for visualizing ideas and concepts. In the next section, we'll explore advanced block configuration options, including setting block widths and creating composite blocks.
## 3. Advanced Block Configuration
Building upon the basics, this section delves into more advanced features of block diagramming in Mermaid. These features allow for greater flexibility and complexity in diagram design, accommodating a wider range of use cases and scenarios.
### Setting Block Width
#### Spanning Multiple Columns
In more complex diagrams, you may need blocks that span multiple columns to emphasize certain components or to represent larger entities. Mermaid allows for the adjustment of block widths to cover multiple columns, enhancing the diagram's readability and structure.
**Example - Block Spanning Multiple Columns**:
To create a block diagram where one block spans across two columns, you can specify the desired width for each block:
```mermaid-example
block-beta
columns 3
a["A label"] b:2 c:2 d
```
```mermaid
block-beta
columns 3
a["A label"] b:2 c:2 d
```
In this example, the block labeled "A wide one" spans two columns, while blocks 'b', 'c', and 'd' are allocated their own columns. This flexibility in block sizing is crucial for accurately representing systems with components of varying significance or size.
### Creating Composite Blocks
#### Nested Blocks
Composite blocks, or blocks within blocks, are an advanced feature in Mermaid's block diagram syntax. They allow for the representation of nested or hierarchical systems, where one component encompasses several subcomponents.
**Example - Composite Blocks:**
Creating a composite block involves defining a parent block and then nesting other blocks within it. Here's how to define a composite block with nested elements:
```mermaid-example
block-beta
block
D
end
A["A: I am a wide one"]
```
```mermaid
block-beta
block
D
end
A["A: I am a wide one"]
```
In this syntax, 'D' is a nested block within a larger parent block. This feature is particularly useful for depicting complex structures, such as a server with multiple services or a department within a larger organizational framework.
### Column Width Dynamics
#### Adjusting Widths
Mermaid also allows for dynamic adjustment of column widths based on the content of the blocks. The width of the columns is determined by the widest block in the column, ensuring that the diagram remains balanced and readable.
**Example - Dynamic Column Widths:**
In diagrams with varying block sizes, Mermaid automatically adjusts the column widths to fit the largest block in each column. Here's an example:
```mermaid-example
block-beta
columns 3
a:3
block:group1:2
columns 2
h i j k
end
g
block:group2:3
%% columns auto (default)
l m n o p q r
end
```
```mermaid
block-beta
columns 3
a:3
block:group1:2
columns 2
h i j k
end
g
block:group2:3
%% columns auto (default)
l m n o p q r
end
```
This example demonstrates how Mermaid dynamically adjusts the width of the columns to accommodate the widest block, in this case, 'a' and the composite block 'e'. This dynamic adjustment is essential for creating visually balanced and easy-to-understand diagrams.
With these advanced configuration options, Mermaid's block diagrams can be tailored to represent a wide array of complex systems and structures. The flexibility offered by these features enables users to create diagrams that are both informative and visually appealing. In the following sections, we will explore further capabilities, including different block shapes and linking options.
## 4. Block Varieties and Shapes
Mermaid's block diagrams are not limited to standard rectangular shapes. A variety of block shapes are available, allowing for a more nuanced and tailored representation of different types of information or entities. This section outlines the different block shapes you can use in Mermaid and their specific applications.
### Standard and Special Block Shapes
Mermaid supports a range of block shapes to suit different diagramming needs, from basic geometric shapes to more specialized forms.
#### Example - Round Edged Block
To create a block with round edges, which can be used to represent a softer or more flexible component:
```mermaid-example
block-beta
id1("This is the text in the box")
```
```mermaid
block-beta
id1("This is the text in the box")
```
#### Example - Stadium-Shaped Block
A stadium-shaped block, resembling an elongated circle, can be used for components that are process-oriented:
```mermaid-example
block-beta
id1(["This is the text in the box"])
```
```mermaid
block-beta
id1(["This is the text in the box"])
```
#### Example - Subroutine Shape
For representing subroutines or contained processes, a block with double vertical lines is useful:
```mermaid-example
block-beta
id1[["This is the text in the box"]]
```
```mermaid
block-beta
id1[["This is the text in the box"]]
```
#### Example - Cylindrical Shape
The cylindrical shape is ideal for representing databases or storage components:
```mermaid-example
block-beta
id1[("Database")]
```
```mermaid
block-beta
id1[("Database")]
```
#### Example - Circle Shape
A circle can be used for centralized or pivotal components:
```mermaid-example
block-beta
id1(("This is the text in the circle"))
```
```mermaid
block-beta
id1(("This is the text in the circle"))
```
#### Example - Asymmetric, Rhombus, and Hexagon Shapes
For decision points, use a rhombus, and for unique or specialized processes, asymmetric and hexagon shapes can be utilized:
**Asymmetric**
```mermaid-example
block-beta
id1>"This is the text in the box"]
```
```mermaid
block-beta
id1>"This is the text in the box"]
```
**Rhombus**
```mermaid-example
block-beta
id1{"This is the text in the box"}
```
```mermaid
block-beta
id1{"This is the text in the box"}
```
**Hexagon**
```mermaid-example
block-beta
id1{{"This is the text in the box"}}
```
```mermaid
block-beta
id1{{"This is the text in the box"}}
```
#### Example - Parallelogram and Trapezoid Shapes
Parallelogram and trapezoid shapes are perfect for inputs/outputs and transitional processes:
```mermaid-example
block-beta
id1[/"This is the text in the box"/]
id2[\"This is the text in the box"\]
A[/"Christmas"\]
B[\"Go shopping"/]
```
```mermaid
block-beta
id1[/"This is the text in the box"/]
id2[\"This is the text in the box"\]
A[/"Christmas"\]
B[\"Go shopping"/]
```
#### Example - Double Circle
For highlighting critical or high-priority components, a double circle can be effective:
```mermaid-example
block-beta
id1((("This is the text in the circle")))
```
```mermaid
block-beta
id1((("This is the text in the circle")))
```
### Block Arrows and Space Blocks
Mermaid also offers unique shapes like block arrows and space blocks for directional flow and spacing.
#### Example - Block Arrows
Block arrows can visually indicate direction or flow within a process:
```mermaid-example
block-beta
blockArrowId<["Label"]>(right)
blockArrowId2<["Label"]>(left)
blockArrowId3<["Label"]>(up)
blockArrowId4<["Label"]>(down)
blockArrowId5<["Label"]>(x)
blockArrowId6<["Label"]>(y)
blockArrowId6<["Label"]>(x, down)
```
```mermaid
block-beta
blockArrowId<["Label"]>(right)
blockArrowId2<["Label"]>(left)
blockArrowId3<["Label"]>(up)
blockArrowId4<["Label"]>(down)
blockArrowId5<["Label"]>(x)
blockArrowId6<["Label"]>(y)
blockArrowId6<["Label"]>(x, down)
```
#### Example - Space Blocks
Space blocks can be used to create intentional empty spaces in the diagram, which is useful for layout and readability:
```mermaid-example
block-beta
columns 3
a space b
c d e
```
```mermaid
block-beta
columns 3
a space b
c d e
```
or
```mermaid-example
block-beta
ida space:3 idb idc
```
```mermaid
block-beta
ida space:3 idb idc
```
Note that you can set how many columns the space block occupied using the number notation `space:num` where num is a number indicating the num columns width. You can also use `space` which defaults to one column.
The variety of shapes and special blocks in Mermaid enhances the expressive power of block diagrams, allowing for more accurate and context-specific representations. These options give users the flexibility to create diagrams that are both informative and visually appealing. In the next sections, we will explore the ways to connect these blocks and customize their appearance.
### Standard and Special Block Shapes
Discuss the various shapes available for blocks, including standard shapes and special forms like block arrows and space blocks.
## 5. Connecting Blocks with Edges
One of the key features of block diagrams in Mermaid is the ability to connect blocks using various types of edges or links. This section explores the different ways blocks can be interconnected to represent relationships and flows between components.
### Basic Linking and Arrow Types
The most fundamental aspect of connecting blocks is the use of arrows or links. These connectors depict the relationships or the flow of information between the blocks. Mermaid offers a range of arrow types to suit different diagramming needs.
**Example - Basic Links**
A simple link with an arrow can be created to show direction or flow from one block to another:
```mermaid-example
block-beta
A space B
A-->B
```
```mermaid
block-beta
A space B
A-->B
```
This example illustrates a direct connection from block 'A' to block 'B', using a straightforward arrow.
This syntax creates a line connecting 'A' and 'B', implying a relationship or connection without indicating a specific direction.
### Text on Links
In addition to connecting blocks, it's often necessary to describe or label the relationship. Mermaid allows for the inclusion of text on links, providing context to the connections.
Example - Text with Links
To add text to a link, the syntax includes the text within the link definition:
```mermaid-example
block-beta
A space:2 B
A-- "X" -->B
```
```mermaid
block-beta
A space:2 B
A-- "X" -->B
```
This example show how to add descriptive text to the links, enhancing the information conveyed by the diagram.
Example - Edges and Styles:
```mermaid-example
block-beta
columns 1
db(("DB"))
blockArrowId6<["&nbsp;&nbsp;&nbsp;"]>(down)
block:ID
A
B["A wide one in the middle"]
C
end
space
D
ID --> D
C --> D
style B fill:#939,stroke:#333,stroke-width:4px
```
```mermaid
block-beta
columns 1
db(("DB"))
blockArrowId6<["&nbsp;&nbsp;&nbsp;"]>(down)
block:ID
A
B["A wide one in the middle"]
C
end
space
D
ID --> D
C --> D
style B fill:#939,stroke:#333,stroke-width:4px
```
## 6. Styling and Customization
Beyond the structure and layout of block diagrams, Mermaid offers extensive styling options. These customization features allow for the creation of more visually distinctive and informative diagrams. This section covers how to apply individual styles to blocks and how to use classes for consistent styling across multiple elements.
### Individual Block Styling
Mermaid enables detailed styling of individual blocks, allowing you to apply various CSS properties such as color, stroke, and border thickness. This feature is especially useful for highlighting specific parts of a diagram or for adhering to certain visual themes.
#### Example - Styling a Single Block
To apply custom styles to a block, you can use the `style` keyword followed by the block identifier and the desired CSS properties:
```mermaid-example
block-beta
id1 space id2
id1("Start")-->id2("Stop")
style id1 fill:#636,stroke:#333,stroke-width:4px
style id2 fill:#bbf,stroke:#f66,stroke-width:2px,color:#fff,stroke-dasharray: 5 5
```
```mermaid
block-beta
id1 space id2
id1("Start")-->id2("Stop")
style id1 fill:#636,stroke:#333,stroke-width:4px
style id2 fill:#bbf,stroke:#f66,stroke-width:2px,color:#fff,stroke-dasharray: 5 5
```
In this example, a class named 'blue' is defined and applied to block 'A', while block 'B' receives individual styling. This demonstrates the flexibility of Mermaid in applying both shared and unique styles within the same diagram.
The ability to style blocks individually or through classes provides a powerful tool for enhancing the visual impact and clarity of block diagrams. Whether emphasizing certain elements or maintaining a cohesive design across the diagram, these styling capabilities are central to effective diagramming. The next sections will present practical examples and use cases, followed by tips for troubleshooting common issues.
### 7. Practical Examples and Use Cases
The versatility of Mermaid's block diagrams becomes evident when applied to real-world scenarios. This section provides practical examples demonstrating the application of various features discussed in previous sections. These examples showcase how block diagrams can be used to represent complex systems and processes in an accessible and informative manner.
### Detailed Examples Illustrating Various Features
Combining the elements of structure, linking, and styling, we can create comprehensive diagrams that serve specific purposes in different contexts.
#### Example - System Architecture
Illustrating a simple software system architecture with interconnected components:
```mermaid-example
block-beta
columns 3
Frontend blockArrowId6<[" "]>(right) Backend
space:2 down<[" "]>(down)
Disk left<[" "]>(left) Database[("Database")]
classDef front fill:#696,stroke:#333;
classDef back fill:#969,stroke:#333;
class Frontend front
class Backend,Database back
```
```mermaid
block-beta
columns 3
Frontend blockArrowId6<[" "]>(right) Backend
space:2 down<[" "]>(down)
Disk left<[" "]>(left) Database[("Database")]
classDef front fill:#696,stroke:#333;
classDef back fill:#969,stroke:#333;
class Frontend front
class Backend,Database back
```
This example shows a basic architecture with a frontend, backend, and database. The blocks are styled to differentiate between types of components.
#### Example - Business Process Flow
Representing a business process flow with decision points and multiple stages:
```mermaid-example
block-beta
columns 3
Start(("Start")) space:2
down<[" "]>(down) space:2
Decision{{"Make Decision"}} right<["Yes"]>(right) Process1["Process A"]
downAgain<["No"]>(down) space r3<["Done"]>(down)
Process2["Process B"] r2<["Done"]>(right) End(("End"))
style Start fill:#969;
style End fill:#696;
```
```mermaid
block-beta
columns 3
Start(("Start")) space:2
down<[" "]>(down) space:2
Decision{{"Make Decision"}} right<["Yes"]>(right) Process1["Process A"]
downAgain<["No"]>(down) space r3<["Done"]>(down)
Process2["Process B"] r2<["Done"]>(right) End(("End"))
style Start fill:#969;
style End fill:#696;
```
These practical examples and scenarios underscore the utility of Mermaid block diagrams in simplifying and effectively communicating complex information across various domains.
The next section, 'Troubleshooting and Common Issues', will provide insights into resolving common challenges encountered when working with Mermaid block diagrams, ensuring a smooth diagramming experience.
## 8. Troubleshooting and Common Issues
Working with Mermaid block diagrams can sometimes present challenges, especially as the complexity of the diagrams increases. This section aims to provide guidance on resolving common issues and offers tips for managing more intricate diagram structures.
### Common Syntax Errors
Understanding and avoiding common syntax errors is key to a smooth experience with Mermaid diagrams.
#### Example - Incorrect Linking
A common mistake is incorrect linking syntax, which can lead to unexpected results or broken diagrams:
block-beta
A - B
**Correction**:
Ensure that links between blocks are correctly specified with arrows (--> or ---) to define the direction and type of connection. Also remember that one of the fundaments for block diagram is to give the author full control of where the boxes are positioned so in the example you need to add a space between the boxes:
```mermaid-example
block-beta
A space B
A --> B
```
```mermaid
block-beta
A space B
A --> B
```
#### Example - Misplaced Styling
Applying styles in the wrong context or with incorrect syntax can lead to blocks not being styled as intended:
```mermaid-example
block-beta
A
style A fill#969;
```
```mermaid
block-beta
A
style A fill#969;
```
**Correction:**
Correct the syntax by ensuring proper separation of style properties with commas and using the correct CSS property format:
```mermaid-example
block-beta
A
style A fill:#969,stroke:#333;
```
```mermaid
block-beta
A
style A fill:#969,stroke:#333;
```
### Tips for Complex Diagram Structures
Managing complexity in Mermaid diagrams involves planning and employing best practices.
#### Modular Design
Break down complex diagrams into smaller, more manageable components. This approach not only makes the diagram easier to understand but also simplifies the creation and maintenance process.
#### Consistent Styling
Use classes to maintain consistent styling across similar elements. This not only saves time but also ensures a cohesive and professional appearance.
#### Comments and Documentation
Use comments with `%%` within the Mermaid syntax to document the purpose of various parts of the diagram. This practice is invaluable for maintaining clarity, especially when working in teams or returning to a diagram after some time.
With these troubleshooting tips and best practices, you can effectively manage and resolve common issues in Mermaid block diagrams. The final section, 'Conclusion', will summarize the key points covered in this documentation and invite user feedback for continuous improvement.

#### Classes
More convenient than defining the style every time is to define a class of styles and attach this class to the nodes that
should have a different look. This is done by predefining classes in css styles that can be applied from the graph definition using the `cssClass` statement or the `:::` short hand.

It is possible to set multiple dependencies separated by space:
Tasks are by default sequential. A task start date defaults to the end date of the preceding task.
A colon, `:`, separates the task title from its metadata.
Metadata items are separated by a comma, `,`. Valid tags are `active`, `done`, `crit`, and `milestone`. Tags are optional, but if used, they must be specified first.
After processing the tags, the remaining metadata items are interpreted as follows:
1. If a single item is specified, it determines when the task ends. It can either be a specific date/time or a duration. If a duration is specified, it is added to the start date of the task to determine the end date of the task, taking into account any exclusions.
2. If two items are specified, the last item is interpreted as in the previous case. The first item can either specify an explicit start date/time (in the format specified by `dateFormat`) or reference another task using `after <otherTaskID> [[otherTaskID2 [otherTaskID3]]...]`. In the latter case, the start date of the task will be set according to the latest end date of any referenced task.
3. If three items are specified, the last two will be interpreted as in the previous case. The first item will denote the ID of the task, which can be referenced using the `later <taskID>` syntax.

### Title
The `title` is an _optional_ string to be displayed at the top of the Gantt chart to describe the chart as a whole.
### Excludes
The `excludes` is an _optional_ attribute that accepts specific dates in YYYY-MM-DD format, days of the week ("sunday") or "weekends", but not the word "weekdays".
These date will be marked on the graph, and be excluded from the duration calculation of tasks. Meaning that if there are excluded dates during a task interval, the number of 'skipped' days will be added to the end of the task to ensure the duration is as specified in the code.
#### Weekend (v\<MERMAID_RELEASE_VERSION>+)
When excluding weekends, it is possible to configure the weekends to be either Friday and Saturday or Saturday and Sunday. By default weekends are Saturday and Sunday.
To define the weekend start day, there is an _optional_ attribute `weekend` that can be added in a new line followed by either `friday` or `saturday`.
```mermaid-example
gantt
title A Gantt Diagram Excluding Fri - Sat weekends

1. You need to provide the `id` for an existing commit to be cherry-picked. If given commit id does not exist it will result in an error. For this, make use of the `commit id:$value` format of declaring commits. See the examples from above.
2. The given commit must not exist on the current branch. The cherry-picked commit must always be a different branch than the current branch.
3. Current branch must have at least one commit, before you can cherry-pick, otherwise it will cause an error is throw.
4. When cherry-picking a merge commit, providing a parent commit ID is mandatory. If the parent attribute is omitted or an invalid parent commit ID is provided, an error will be thrown.
5. The specified parent commit must be an immediate parent of the merge commit being cherry-picked.

# Packet Diagram (v\<MERMAID_RELEASE_VERSION>+)
## Introduction
A packet diagram is a visual representation used to illustrate the structure and contents of a network packet. Network packets are the fundamental units of data transferred over a network.
## Usage
This diagram type is particularly useful for network engineers, educators, and students who require a clear and concise way to represent the structure of network packets.
## Syntax
```md
packet-beta
start: "Block name" %% Single-bit block
start-end: "Block name" %% Multi-bit blocks
... More Fields ...
```
## Examples
```mermaid-example
---
title: "TCP Packet"
---
packet-beta
0-15: "Source Port"
16-31: "Destination Port"
32-63: "Sequence Number"

96-99: "Data Offset"
100-105: "Reserved"
106: "URG"
107: "ACK"
108: "PSH"
109: "RST"
110: "SYN"
111: "FIN"
112-127: "Window"
128-143: "Checksum"
144-159: "Urgent Pointer"
160-191: "(Options and Padding)"
192-255: "Data (variable length)"
```

16-31: "Destination Port"
32-47: "Length"
48-63: "Checksum"
64-95: "Data (variable length)"
```
## Details of Syntax
- **Ranges**: Each line after the title represents a different field in the packet. The range (e.g., `0-15`) indicates the bit positions in the packet.
- **Field Description**: A brief description of what the field represents, enclosed in quotes.
## Configuration
Please refer to the [configuration](/config/schema-docs/config-defs-packet-diagram-config.html) guide for details.
<!--
Theme variables are not currently working due to a mermaid bug. The passed values are not being propagated into styles function.

It is usually presented graphically to indicate the passing of time, and it is usually organized chronologically. A basic timeline presents a list of events in chronological order, usually using dates as markers. A timeline can also be used to show the relationship between events, such as the relationship between the events of a person's life." Wikipedia

# XY Chart
> In the context of mermaid-js, the XY chart is a comprehensive charting module that encompasses various types of charts that utilize both x-axis and y-axis for data representation. Presently, it includes two fundamental chart types: the bar chart and the line chart. These charts are designed to visually display and analyze data that involve two numerical variables.
> It's important to note that while the current implementation of mermaid-js includes these two chart types, the framework is designed to be dynamic and adaptable. Therefore, it has the capacity for expansion and the inclusion of additional chart types in the future. This means that users can expect an evolving suite of charting options within the XY chart module, catering to various data visualization needs as new chart types are introduced over time.
## Example
```mermaid-example
xychart-beta
title "Sales Revenue"
x-axis [jan, feb, mar, apr, may, jun, jul, aug, sep, oct, nov, dec]
y-axis "Revenue (in $)" 4000 --> 11000
bar [5000, 6000, 7500, 8200, 9500, 10500, 11000, 10200, 9200, 8500, 7000, 6000]
line [5000, 6000, 7500, 8200, 9500, 10500, 11000, 10200, 9200, 8500, 7000, 6000]
```
```mermaid
xychart-beta
title "Sales Revenue"
x-axis [jan, feb, mar, apr, may, jun, jul, aug, sep, oct, nov, dec]
y-axis "Revenue (in $)" 4000 --> 11000
bar [5000, 6000, 7500, 8200, 9500, 10500, 11000, 10200, 9200, 8500, 7000, 6000]
line [5000, 6000, 7500, 8200, 9500, 10500, 11000, 10200, 9200, 8500, 7000, 6000]
```
## Syntax
> **Note**
> All text values that contain only one word can be written without `"`. If a text value has many words in it, specifically if it contains spaces, enclose the value in `"`
### Orientations
The chart can be drawn horizontal or vertical, default value is vertical.
xychart-beta horizontal
...
### Title
The title is a short description of the chart and it will always render on top of the chart.
#### Example
xychart-beta
title "This is a simple example"
...
> **Note**
> If the title is a single word one no need to use `"`, but if it has space `"` is needed
### x-axis
The x-axis primarily serves as a categorical value, although it can also function as a numeric range value when needed.
#### Example
1. `x-axis title min --> max` x-axis will function as numeric with the given range
2. `x-axis "title with space" [cat1, "cat2 with space", cat3]` x-axis if categorical, categories are text type
### y-axis
The y-axis is employed to represent numerical range values, it cannot have categorical values.
#### Example
1. `y-axis title min --> max`
2. `y-axis title` it will only add the title, the range will be auto generated from data.
> **Note**
> Both x and y axis are optional if not provided we will try to create the range
### Line chart
A line chart offers the capability to graphically depict lines.
#### Example
1. `line [2.3, 45, .98, -3.4]` it can have all valid numeric values.
### Bar chart
A bar chart offers the capability to graphically depict bars.
#### Example
1. `bar [2.3, 45, .98, -3.4]` it can have all valid numeric values.
#### Simplest example
The only two things required are the chart name (`xychart-beta`) and one data set. So you will be able to draw a chart with a simple config like
xychart-beta
line [+1.3, .6, 2.4, -.34]
