What is a Multi-Layer Pie Chart?
A multi-layer pie chart is a circular data visualization that uses concentric rings to represent hierarchical or categorical data at multiple levels simultaneously. Unlike a standard pie chart that shows only one level of categories, multi-layer pie charts add depth by nesting related subcategories in outer rings around a central pie. This family of charts includes sunburst diagrams, nested donut charts, and concentric ring charts. They are particularly valuable in research and business analytics for revealing how broad categories decompose into finer sub-groups, making complex hierarchical datasets immediately understandable at a glance.
Types of Multi-Layer Pie Charts
- Sunburst Chart - A radial hierarchy chart where each ring represents a level in the data tree, expanding outward from a central root category to leaf nodes
- Nested Donut Chart - Concentric donut rings where each ring shows a different categorical dimension, with segments aligned to show part-to-whole relationships
- Concentric Ring Chart - Multiple independent ring layers stacked concentrically, each displaying a separate variable or time period for comparison
- Hierarchical Pie Chart - A standard pie chart with drilldown layers that reveal subcategories within each slice of the parent chart
- Multi-Ring Donut - A donut chart with two or more rings sharing the same center hole, often used to compare proportions across different groups or time periods
- Radial Treemap - A circular variant of a treemap that arranges hierarchical data in nested arcs rather than rectangles
When to Use Multi-Layer Pie Charts
Multi-layer pie charts are ideal when your data has a natural hierarchy and you want to show how subcategories contribute to parent categories. Use them for budget breakdowns where departments split into cost centers, market analysis where industries decompose into segments, population studies with nested demographic layers, and organizational charts showing divisions down to teams. They work best with 2-3 levels of hierarchy and fewer than 20 total segments. Avoid them when precise numerical comparison is more important than showing hierarchical structure, as the curved segments can make exact value estimation difficult.
How to Read a Multi-Layer Pie Chart
Start reading a multi-layer pie chart from the center outward. The innermost ring shows the top-level categories and their proportions. Each subsequent outer ring breaks those categories into finer subcategories. The angular width of each segment is proportional to its value relative to its parent segment. Color coding connects related segments across rings, so segments in the same color family belong to the same parent category. To understand a specific data point, trace its arc inward to identify which parent categories it belongs to. The total arc of all child segments always equals the arc of their parent segment, maintaining the part-to-whole relationship at every level.
Best Practices for Multi-Layer Pie Chart Design
- Limit hierarchy to 2-3 rings to maintain readability and avoid visual overload
- Use consistent color families where subcategories share lighter or darker shades of their parent color
- Label segments directly when space permits, and use a legend for smaller slices
- Include percentage values on each segment so readers can estimate proportions accurately
- Order segments by size within each ring, placing the largest slice at the 12 o-clock position
- Add a center label or title inside the donut hole to describe the total or dataset name
- Ensure adequate contrast between adjacent segments, especially in the outer rings where slices are narrower
