Zoomable Treemap
Explore hierarchical data as nested rectangles sized by value with interactive zoom. Rectangle area directly encodes the underlying measure, making it easy to spot the largest items at a glance. Click any cell to drill into its children. Ideal for disk usage, market capitalization, and budget analysis.
Examples
When to Use
- Spotting the largest categories at a glance in a flat or nested hierarchy
- Disk usage, market cap, or revenue breakdown by segment
