composition family
sunburst
Radial concentric rings showing hierarchical composition.
Treemap rotated to a radial layout. Each ring is a level of hierarchy; angle encodes share. Visually striking; harder to read precisely than a treemap.
When to use
Multi-level taxonomy where the radial form is part of the brand or where the chart is hero on a slide.
When NOT to use
Reader needs precise comparisons (use treemap or stacked bar).
