About Treemap Chart
Treemap Chart packs items into tiles sized by value, tinted green or red by their change, springing in from their centres. Labels only appear where they fit, so small tiles stay clean instead of cramming text.
Treemap Chart is an animated chart for React 19, styled with Tailwind CSS 4 and animated with Motion. It drops into Next.js, Vite, Remix or Astro through the shadcn CLI as a single file you own.
When to use Treemap Chart
- Market and sector heatmaps.
- Disk usage and storage breakdowns.
- Budget and spend allocation.
- Portfolio weights.
How it works
The squarified layout keeps tiles close to square for easy comparison. Tint strength scales with the size of the change, and each tile carries its name, value and change as an accessible label.
Each chart has a text alternative, hover tooltips are mirrored by keyboard focus where data points are interactive, and colour is never the only way a value is shown. With prefers-reduced-motion on, it holds still or settles instantly instead of animating.
Customizing Treemap Chart
Every prop is documented in the API reference above with its type and default. The ones you will reach for first are listed here.
The Customize panel next to the preview lets you change height live, and the Code tab updates to match, so the snippet you copy already carries your values.
- items.
- width / height (number, default 640 / 360).
- format ((v: number) => string).
- title (string).
