About Treemap Charts
When to Use Treemap Charts
Treemap charts are perfect for visualizing hierarchical data where you need to show both the relative size and categorical relationships of different elements. Use treemaps when displaying market share analysis, budget allocations, portfolio compositions, organizational structures, or any dataset where you want to compare proportional values across categories like Technology, Healthcare, Finance, Consumer Goods, and Energy sectors. They excel at revealing patterns in complex datasets by using area size to represent quantitative values while maintaining clear visual separation between categories.
