Treemap
Many parts in groups, sized by value.
Definition · Updated Nov 2, 2026
A treemap fills a rectangle with tiles sized by value and grouped by category, so the big sellers and the long tail show in one view. Use it for sales by category and subcategory, spend by team or storage by folder.

Treemap questions.
What people ask before they put a treemap in a dashboard.
Something else?
hello@usechartory.comTiles too small for a value show only their name, and tiles too narrow or short for a name show nothing at M. The category colour and the size still place them.
Each category takes one colour and its tiles sit together. The legend names the four categories.
One data object in the sample’s shape: parts with a value, grouped in categories. The docs page lists every field and links its JSON Schema; the sample data comes with the component, so you can start from it and swap in your own.
Series take the preset’s data colours in order, and states such as up, down or warning take its status colours. Change the preset in Figma or in code to recolour every chart at once.
XS, S, M and L, in light and dark. Each size is laid out again from the data, so text and lines keep their size.
Yes. It plays in when it scrolls into view, and when the data changes every mark moves from its old place to its new one. With reduced motion on, it does not move.
Yes. The React component is free in the public registry in Hearth, no token needed; Signal comes with Code and Complete. The Figma component comes with Figma and Complete.
Ask for it by name. The MCP server tells the agent what data it needs and runs the same command: npx shadcn add @chartory/treemap. You review the diff.
