A Treemap Chart represents hierarchical data as nested rectangles whose size and color encode numeric values. This format is ideal for part-to-whole comparisons across multiple levels of a hierarchy.
This sample breaks down the chemical composition of an average 70 kg human body. Major elements like oxygen and carbon appear as large cells, while trace elements nest inside an "Other" parent category with further sub-levels. A linear color scale ranging from light gold to pink reflects each element’s mass. Hover over any cell to view its essentiality status and the positive or negative effects of excess amounts.
Follow the step-by-step Treemap Chart Tutorial to learn how such charts are built. See the Treemap Chart documentation for all configuration options.
