What is a Treemap?
Treemaps visualize hierarchical data structures by dividing a rectangle into smaller rectangles, with each rectangle's size proportional to its value and color often representing another dimension. Treemaps efficiently display large datasets with multiple levels of hierarchy while using screen space optimally. They're particularly useful for understanding composition and finding patterns in hierarchical data.
Treemaps excel at showing market share across multiple product categories, displaying organizational structures by budget allocation, or visualizing file system usage across directories. The nested rectangle approach makes it easy to see both the big picture and drill down into specific segments. Treemaps are more space-efficient than sunburst or pie charts for displaying complex hierarchies.
