Treemap

Treemaps visualize hierarchical data by nesting rectangles within rectangles, where the size of each rectangle is proportional to its value. They efficiently use space while showing part-to-whole relationships across multiple levels. Treemaps are excellent for visualizing file system storage, market sectors, organizational budgets, and any nested categorical data with associated quantities.
