A Treemap Chart displays hierarchical data as nested rectangles, where the size and color of each cell reflect its value. This visualization makes it easy to compare items within and across categories at a glance.
This sample maps average annual revenue for 40 ACME food products grouped into four categories: fruits, vegetables, dairy, and meat. An ordinal color scale with six revenue brackets shades cells from yellow to dark green, while a vertical legend on the right decodes each bracket. Click any category header to drill down into its products, and hover over a cell to see the exact dollar amount in a formatted tooltip.
Follow the step-by-step Treemap Chart Tutorial to learn how such charts are built. See the Treemap Chart documentation for all configuration options.
