+# Quadrant Chart
+
+> A quadrant chart is a visual representation of data that is divided into four quadrants. It is used to plot data points on a two-dimensional grid, with one variable represented on the x-axis and another variable represented on the y-axis. The quadrants are determined by dividing the chart into four equal parts based on a set of criteria that is specific to the data being analyzed. Quadrant charts are often used to identify patterns and trends in data, and to prioritize actions based on the position of data points within the chart. They are commonly used in business, marketing, and risk management, among other fields.

+## Example

+```mermaid-example

+
+## Syntax
+
+> **Note**
+> In place of `<text>` you can use text like `this is a sample text` or inside **double quotes** like `"This type of text may contain unicode like ❤"`.
+
+> **Note**
+> If there is no points available in the chart both **axis** text and **quadrant** will be rendered in the center of the respective quadrant.
+> If there are points **x-axis** labels will rendered from left of the respective quadrant also they will be displayed in bottom of the chart, and **y-axis** lables will be rendered in bottom of the respective quadrant, the quadrant text will render at top of the respective quadrant.
+
+> **Note**
+> For points x and y value min value is 0 and max value is 1.
+
+### Title
+
+The title is a short description of the chart and it will always render on top of the chart.
+
+#### Example
+
+    quadrantChart
+        title This is a sample example
+
+### x-axis
+
+The x-axis determine what text would be displayed in the x-axis. In x-axis there is two part **left** and **right** you can pass **both** or you can pass only **left**. The statement should start with `x-axis` then the `left axis text` followed by the delimiter `-->` then `right axis text`.
+
+#### Example
+
+1.  `x-axis <text> --> <text>` both the left and right axis text will be rendered.
+2.  `x-axis <text>` only the left axis text will be rendered.
+
+### y-axis
+
+The y-axis determine what text would be displayed in the y-axis. In y-axis there is two part **top** and **bottom** you can pass **both** or you can pass only **bottom**. The statement should start with `y-axis` then the `bottom axis text` followed by the delimiter `-->` then `top axis text`.
+
+#### Example
+
+1.  `y-axis <text> --> <text>` both the bottom and top axis text will be rendered.
+2.  `y-axis <text>` only the bottom axis text will be rendered.
+
+### Quadrants text
+
+The `quadrant-[1,2,3,4]` determine what text would be displayed inside the quadrants.
+
+#### Example
+
+1.  `quadrant-1 <text>` determine what text will be rendered inside the top right quadrant.
+2.  `quadrant-2 <text>` determine what text will be rendered inside the top left quadrant.
+3.  `quadrant-3 <text>` determine what text will be rendered inside the bottom left quadrant.
+4.  `quadrant-4 <text>` determine what text will be rendered inside the bottom right quadrant.
+
+### Points
+
+Points are used to plot a circle inside the quadrantChart. The syntax is `<text>: [x, y]` here x and y value is in the range 0 - 1.
+
+#### Example
+
+1.  `Point 1: [0.75, 0.80]` here the Point 1 will be drawn in the top right quadrant.
+2.  `Point 2: [0.35, 0.24]` here the Point 2 will be drawn in the bottom left quadrant.

+# ZenUML
+
+> A Sequence diagram is an interaction diagram that shows how processes operate with one another and in what order.
+
+Mermaid can render sequence diagrams with [ZenUML](https://zenuml.com). Note that ZenUML uses a different
+syntax than the original Sequence Diagram in mermaid.
+
+```mermaid-example
+zenuml
+    title Demo
+    Alice->John: Hello John, how are you?
+    John->Alice: Great!
+    Alice->John: See you later!
+```
+
+```mermaid
+zenuml
+    title Demo
+    Alice->John: Hello John, how are you?
+    John->Alice: Great!
+    Alice->John: See you later!
+```
+
+## Syntax
+
+### Participants
+
+The participants can be defined implicitly as in the first example on this page. The participants or actors are
+rendered in order of appearance in the diagram source text. Sometimes you might want to show the participants in a
+different order than how they appear in the first message. It is possible to specify the actor's order of
+appearance by doing the following:
+
+```mermaid-example
+zenuml
+    title Declare participant (optional)
+    Bob
+    Alice
+    Alice->Bob: Hi Bob
+    Bob->Alice: Hi Alice
+```
+
+```mermaid
+zenuml
+    title Declare participant (optional)
+    Bob
+    Alice
+    Alice->Bob: Hi Bob
+    Bob->Alice: Hi Alice
+```
+
+### Annotators
+
+If you specifically want to use symbols instead of just rectangles with text you can do so by using the annotator syntax to declare participants as per below.
+
+```mermaid-example
+zenuml
+    title Annotators
+    @Actor Alice
+    @Database Bob
+    Alice->Bob: Hi Bob
+    Bob->Alice: Hi Alice
+```
+
+```mermaid
+zenuml
+    title Annotators
+    @Actor Alice
+    @Database Bob
+    Alice->Bob: Hi Bob
+    Bob->Alice: Hi Alice
+```
+
+Here are the available annotators:
+![img.png](img/zenuml-participant-annotators.png)
+
+### Aliases
+
+The participants can have a convenient identifier and a descriptive label.
+
+```mermaid-example
+zenuml
+    title Aliases
+    A as Alice
+    J as John
+    A->J: Hello John, how are you?
+    J->A: Great!
+```
+
+```mermaid
+zenuml
+    title Aliases
+    A as Alice
+    J as John
+    A->J: Hello John, how are you?
+    J->A: Great!
+```
+
+## Messages
+
+Messages can be one of:
+
+1.  Sync message
+2.  Async message
+3.  Creation message
+4.  Reply message
+
+### Sync message
+
+You can think of a sync (blocking) method in a programming language.
+
+```mermaid-example
+zenuml
+    title Sync message
+    A.SyncMessage
+    A.SyncMessage(with, parameters) {
+      B.nestedSyncMessage()
+    }
+```
+
+```mermaid
+zenuml
+    title Sync message
+    A.SyncMessage
+    A.SyncMessage(with, parameters) {
+      B.nestedSyncMessage()
+    }
+```
+
+### Async message
+
+You can think of an async (non-blocking) method in a programming language.
+Fire an event and forget about it.
+
+```mermaid-example
+zenuml
+    title Async message
+    Alice->Bob: How are you?
+```
+
+```mermaid
+zenuml
+    title Async message
+    Alice->Bob: How are you?
+```
+
+### Creation message
+
+We use `new` keyword to create an object.
+
+```mermaid-example
+zenuml
+    new A1
+    new A2(with, parameters)
+```
+
+```mermaid
+zenuml
+    new A1
+    new A2(with, parameters)
+```
+
+### Reply message
+
+There are three ways to express a reply message:
+
+```mermaid-example
+zenuml
+    // 1. assign a variable from a sync message.
+    a = A.SyncMessage()
+
+    // 1.1. optionally give the variable a type
+    SomeType a = A.SyncMessage()
+
+    // 2. use return keyword
+    A.SyncMessage() {
+    return result
+    }
+
+    // 3. use @return or @reply annotator on an async message
+    @return
+    A->B: result
+```
+
+```mermaid
+zenuml
+    // 1. assign a variable from a sync message.
+    a = A.SyncMessage()
+
+    // 1.1. optionally give the variable a type
+    SomeType a = A.SyncMessage()
+
+    // 2. use return keyword
+    A.SyncMessage() {
+    return result
+    }
+
+    // 3. use @return or @reply annotator on an async message
+    @return
+    A->B: result
+```
+
+The third way `@return` is rarely used, but it is useful when you want to return to one level up.
+
+```mermaid-example
+zenuml
+    title Reply message
+    Client->A.method() {
+      B.method() {
+        if(condition) {
+          return x1
+          // return early
+          @return
+          A->Client: x11
+        }
+      }
+      return x2
+    }
+```
+
+```mermaid
+zenuml
+    title Reply message
+    Client->A.method() {
+      B.method() {
+        if(condition) {
+          return x1
+          // return early
+          @return
+          A->Client: x11
+        }
+      }
+      return x2
+    }
+```
+
+## Nesting
+
+Sync messages and Creation messages are naturally nestable with `{}`.
+
+```mermaid-example
+zenuml
+    A.method() {
+      B.nested_sync_method()
+      B->C: nested async message
+    }
+```
+
+```mermaid
+zenuml
+    A.method() {
+      B.nested_sync_method()
+      B->C: nested async message
+    }
+```
+
+## Comments
+
+It is possible to add comments to a sequence diagram with `// comment` syntax.
+Comments will be rendered above the messages or fragments. Comments on other places
+are ignored. Markdown is supported.
+
+See the example below:
+
+```mermaid-example
+zenuml
+    // a comment on a participant will not be rendered
+    BookService
+    // a comment on a message.
+    // **Markdown** is supported.
+    BookService.getBook()
+```
+
+```mermaid
+zenuml
+    // a comment on a participant will not be rendered
+    BookService
+    // a comment on a message.
+    // **Markdown** is supported.
+    BookService.getBook()
+```
+
+## Loops
+
+It is possible to express loops in a ZenUML diagram. This is done by any of the
+following notations:
+
+1.  while
+2.  for
+3.  forEach, foreach
+4.  loop
+
+```zenuml
+while(condition) {
+    ...statements...
+}
+```
+
+See the example below:
+
+```mermaid-example
+zenuml
+    Alice->John: Hello John, how are you?
+    while(true) {
+      John->Alice: Great!
+    }
+```
+
+```mermaid
+zenuml
+    Alice->John: Hello John, how are you?
+    while(true) {
+      John->Alice: Great!
+    }
+```
+
+## Alt
+
+It is possible to express alternative paths in a sequence diagram. This is done by the notation
+
+```zenuml
+if(condition1) {
+    ...statements...
+} else if(condition2) {
+    ...statements...
+} else {
+    ...statements...
+}
+```
+
+See the example below:
+
+```mermaid-example
+zenuml
+    Alice->Bob: Hello Bob, how are you?
+    if(is_sick) {
+      Bob->Alice: Not so good :(
+    } else {
+      Bob->Alice: Feeling fresh like a daisy
+    }
+```
+
+```mermaid
+zenuml
+    Alice->Bob: Hello Bob, how are you?
+    if(is_sick) {
+      Bob->Alice: Not so good :(
+    } else {
+      Bob->Alice: Feeling fresh like a daisy
+    }
+```
+
+## Opt
+
+It is possible to render an `opt` fragment. This is done by the notation
+
+```zenuml
+opt {
+  ...statements...
+}
+```
+
+See the example below:
+
+```mermaid-example
+zenuml
+    Alice->Bob: Hello Bob, how are you?
+    Bob->Alice: Not so good :(
+    opt {
+      Bob->Alice: Thanks for asking
+    }
+```
+
+```mermaid
+zenuml
+    Alice->Bob: Hello Bob, how are you?
+    Bob->Alice: Not so good :(
+    opt {
+      Bob->Alice: Thanks for asking
+    }
+```
+
+## Parallel
+
+It is possible to show actions that are happening in parallel.
+
+This is done by the notation
+
+```zenuml
+par {
+  statement1
+  statement2
+  statement3
+}
+```
+
+See the example below:
+
+```mermaid-example
+zenuml
+    par {
+        Alice->Bob: Hello guys!
+        Alice->John: Hello guys!
+    }
+```
+
+```mermaid
+zenuml
+    par {
+        Alice->Bob: Hello guys!
+        Alice->John: Hello guys!
+    }
+```
+
+## Try/Catch/Finally (Break)
+
+It is possible to indicate a stop of the sequence within the flow (usually used to model exceptions).
+
+This is done by the notation
+
+    try {
+      ...statements...
+    } catch {
+      ...statements...
+    } finally {
+      ...statements...
+    }
+
+See the example below:
+
+```mermaid-example
+zenuml
+    try {
+      Consumer->API: Book something
+      API->BookingService: Start booking process
+    } catch {
+      API->Consumer: show failure
+    } finally {
+      API->BookingService: rollback status
+    }
+```
+
+```mermaid
+zenuml
+    try {
+      Consumer->API: Book something
+      API->BookingService: Start booking process
+    } catch {
+      API->Consumer: show failure
+    } finally {
+      API->BookingService: rollback status
+    }
+```
+
+## Integrating with your library/website.
+
+Zenuml uses the experimental lazy loading & async rendering features which could change in the future.
+
+You can use this method to add mermaid including the zenuml diagram to a web page:
+
+```html
+<script type="module">
+  import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs';
+  import zenuml from 'https://cdn.jsdelivr.net/npm/@mermaid-js/mermaid-zenuml@0.1.0/dist/mermaid-zenuml.esm.min.mjs';
+  await mermaid.registerExternalDiagrams([zenuml]);
+</script>
+```
