+# Treemap Diagram
 
-Treemap diagrams are useful for visualizing hierarchical structures where the size of each rectangle can represent a quantitative value.
+> A treemap diagram displays hierarchical data as a set of nested rectangles. Each branch of the tree is represented by a rectangle, which is then tiled with smaller rectangles representing sub-branches.
+
+> **Warning**
+> This is a new diagram type in Mermaid. Its syntax may evolve in future versions.
+
+## Introduction
+
+Treemap diagrams are an effective way to visualize hierarchical data and show proportions between categories and subcategories. The size of each rectangle is proportional to the value it represents, making it easy to compare different parts of a hierarchy.
+
+Treemap diagrams are particularly useful for:
+
+- Visualizing hierarchical data structures
+- Comparing proportions between categories
+- Displaying large amounts of hierarchical data in a limited space
+- Identifying patterns and outliers in hierarchical data
 
 ## Syntax
 
-The syntax for creating a treemap is straightforward. It uses indentation to define the hierarchy and allows you to specify values for the leaf nodes.
-
 ```
 treemap
-    Root
+"Section 1"
-        Branch 1
+    "Leaf 1.1": 12
-            Leaf 1.1: 10
+    "Section 1.2"
-            Leaf 1.2: 15
+      "Leaf 1.2.1": 12
-        Branch 2
+"Section 2"
-            Leaf 2.1: 20
+    "Leaf 2.1": 20
-            Leaf 2.2: 25
+    "Leaf 2.2": 25
 ```
 
-In the example above:
+### Node Definition
-- `Root` is the top-level node
+
-- `Branch 1` and `Branch 2` are children of `Root`
+Nodes in a treemap are defined using the following syntax:
-- The leaf nodes (`Leaf 1.1`, etc.) have values specified after a colon
+
+- **Section/Parent nodes**: Defined with quoted text `"Section Name"`
+- **Leaf nodes with values**: Defined with quoted text followed by a colon and value `"Leaf Name": value`
+- **Hierarchy**: Created using indentation (spaces or tabs)
+- **Styling**: Nodes can be styled using the `:::class` syntax
 
 ## Examples
 
 ### Basic Treemap
 
-```mermaid
+```mermaid-example
 treemap
-    Root
+"Category A"
-        Branch 1

-            Leaf 1.1: 10
+    "Item A2": 20
-            Leaf 1.2: 15
+"Category B"
-        Branch 2
+    "Item B1": 15
-            Leaf 2.1: 20
+    "Item B2": 25

-## Configuration
+### Treemap with Styling
 
-You can configure the appearance of treemap diagrams in your Mermaid configuration:
+```mermaid-example
+treemap
+"Section 1"
+    "Leaf 1.1": 12
+    "Section 1.2":::class1
+      "Leaf 1.2.1": 12
+"Section 2"
+    "Leaf 2.1": 20:::class1
+    "Leaf 2.2": 25
+    "Leaf 2.3": 12
 
-```javascript
+classDef class1 fill:red,color:blue,stroke:#FFD600;
-mermaid.initialize({
-  treemap: {
-    useMaxWidth: true,
-    padding: 10,
-    showValues: true,
-    nodeWidth: 100,
-    nodeHeight: 40,
-    borderWidth: 1,
-    valueFontSize: 12,
-    labelFontSize: 14,
-    valueFormat: ','
-  }
-});
 ```
 
-Key configuration options:
+```mermaid
+treemap
+"Section 1"
+    "Leaf 1.1": 12
+    "Section 1.2":::class1
+      "Leaf 1.2.1": 12
+"Section 2"
+    "Leaf 2.1": 20:::class1
+    "Leaf 2.2": 25
+    "Leaf 2.3": 12

-|--------------|--------------------------------------------|---------|

-| useMaxWidth  | Use available width to scale the diagram   | true    |
-| padding      | Padding between nodes                      | 10      |
-| showValues   | Show values in leaf nodes                  | true    |
-| nodeWidth    | Default width of nodes                     | 100     |

-| labelFontSize| Font size for node labels                  | 14      |
-| valueFormat  | Format string for values (D3 format)       | ','     |
 
-## Value Formatting
+## Styling and Configuration
 
-You can customize how values are displayed in the treemap using the `valueFormat` configuration option. This option primarily uses [D3's format specifiers](https://github.com/d3/d3-format#locale_format) to control how numbers are displayed, with some additional special cases for common formats.
+Treemap diagrams can be customized using Mermaid's styling and configuration options.
+
+### Using classDef for Styling
+
+You can define custom styles for nodes using the `classDef` syntax, which is a standard feature across many Mermaid diagram types:
+
+```mermaid-example
+treemap
+"Main"
+    "A": 20
+    "B":::important
+        "B1": 10
+        "B2": 15
+    "C": 5
+
+classDef important fill:#f96,stroke:#333,stroke-width:2px;
+```
+
+```mermaid
+treemap
+"Main"
+    "A": 20
+    "B":::important
+        "B1": 10
+        "B2": 15
+    "C": 5
+
+classDef important fill:#f96,stroke:#333,stroke-width:2px;
+```
+
+### Theme Configuration
+
+You can customize the colors of your treemap using the theme configuration:
+
+```mermaid-example
+%%{init: {'theme': 'forest'}}%%
+treemap
+"Category A"
+    "Item A1": 10
+    "Item A2": 20
+"Category B"
+    "Item B1": 15
+    "Item B2": 25
+```
+
+```mermaid
+%%{init: {'theme': 'forest'}}%%
+treemap
+"Category A"
+    "Item A1": 10
+    "Item A2": 20
+"Category B"
+    "Item B1": 15
+    "Item B2": 25
+```
+
+### Directives
+
+You can use directives to customize the appearance of your treemap:
+
+```mermaid-example
+%%{init: {'treemap': {'useWidth': true, 'useHeight': true}}}%%
+treemap
+"Category A"
+    "Item A1": 10
+    "Item A2": 20
+"Category B"
+    "Item B1": 15
+    "Item B2": 25
+```
+
+```mermaid
+%%{init: {'treemap': {'useWidth': true, 'useHeight': true}}}%%

+    "Item A1": 10

-## Notes and Limitations
+## Common Use Cases
 
-- The treemap diagram is designed for hierarchical visualization only
+Treemap diagrams are commonly used for:
-- Deep hierarchies may result in very small rectangles that are difficult to read
-- For best results, limit your hierarchy to 3-4 levels
-- Values should be provided only for leaf nodes
 
-## Styling
+1. **Financial Data**: Visualizing budget allocations, market shares, or portfolio compositions
+2. **File System Analysis**: Showing disk space usage by folders and files
+3. **Population Demographics**: Displaying population distribution across regions and subregions
+4. **Product Hierarchies**: Visualizing product categories and their sales volumes
+5. **Organizational Structures**: Representing departments and team sizes in a company
 
-You can style the different elements of the treemap using CSS. The key classes are:
+## Limitations
 
-- `.treemapNode` - All nodes
+- Treemap diagrams work best when the data has a natural hierarchy
-- `.treemapSection` - Non-leaf nodes
+- Very small values may be difficult to see or label in a treemap diagram
-- `.treemapLeaf` - Leaf nodes
+- Deep hierarchies (many levels) can be challenging to represent clearly
-- `.treemapLabel` - Node labels
+- Treemap diagrams are not well suited for representing data with negative values
-- `.treemapValue` - Node values
+
-- `.treemapTitle` - Diagram title
+## Related Diagrams
+
+If treemap diagrams don't suit your needs, consider these alternatives:
+
+- **Pie Charts**: For simple proportion comparisons without hierarchy
+- **Sunburst Diagrams**: For hierarchical data with a radial layout (yet to be released in Mermaid).
+- **Sankey Diagrams**: For flow-based hierarchical data
+
+## Notes
+
+The treemap diagram implementation in Mermaid is designed to be simple to use while providing powerful visualization capabilities. As this is a newer diagram type, feedback and feature requests are welcome through the Mermaid GitHub repository.
