Syncfusion.Blazor.TreeMap 35.1.40

Syncfusion Blazor TreeMap

The Syncfusion Blazor TreeMap component visualizes hierarchical and flat data using nested rectangles with customizable colors, labels, and legends. Perfect for displaying complex data structures and hierarchies in modern Blazor applications.

Using this package with an AI coding agent

Before generating Syncfusion code, ask your AI coding agent to run the Syncfusion setup using the following prompt:

Set up this project for Syncfusion before generating code. Fetch and follow the official instructions at https://ai.syncfusion.com, then report the detected platform, installed skill pack, MCP status, and any required licensing action.

The setup detects your project's platform and loads the appropriate Syncfusion skill pack. No Syncfusion account or MCP key is required to install or read Syncfusion agent skills.

Key features

• Multiple layout algorithms - Choose from several layout modes, including Squarified, Horizontal Slice‑and‑Dice, Vertical Slice‑and‑Dice, and Auto layouts to best represent your data.
• Interactive selection & Highlighting - Highlight or select specific nodes on hover or click to focus user attention on key items.
• Responsive & mobile‑friendly design - Automatically adapts to all screen sizes with optimized rendering across desktops, tablets, and mobile devices.
