A Treemap Chart arranges hierarchical data as proportionally sized rectangles colored by a scale that reflects each value. This makes it intuitive to identify the largest and smallest entries across multiple levels of a dataset.
This sample displays U.S. population data organized by state and major city. A linear color scale from orange (lower population) to red (higher population) maps the relative size of each area. Labels show the name and population count at every level, and tooltips provide formatted population figures. Click any state to drill down into its most populated cities.
Follow the step-by-step Treemap Chart Tutorial to learn how such charts are built. See the Treemap Chart documentation for all configuration options.
