A multi-level pie chart showing hierarchical data in concentric rings. The innermost ring represents the top level, with each successive ring representing a deeper level in the hierarchy, making it easy to see both structure and proportion.

Best for
- Showing hierarchical data with proportional relationships
- Displaying multi-level part-to-whole breakdowns
- Exploring nested categorical data interactively
Avoid when
- The hierarchy has many small leaf nodes — they become unreadable
- You need precise value comparisons between items
- The data has more than 3–4 levels of nesting
