Voronoi Treemap

A treemap variant using organic, cell-like shapes instead of rectangles for a more natural appearance. Voronoi tessellation creates irregular polygons whose areas are proportional to values, offering a visually distinctive alternative to standard treemaps.

Best for

  • Creating visually distinctive hierarchy visualizations
  • Showing proportional data with a more organic aesthetic
  • Presenting data where rigid rectangles feel too sterile

Avoid when

  • You need precise size comparisons — irregular shapes are harder to compare
  • The audience expects traditional chart styles
  • You need to show labels inside very small cells
