Free Multi-Layer Pie Chart Maker

A multi-layer pie chart is a pie chart made of two or more concentric rings, where the inner ring shows top-level categories and each outer ring breaks those categories into subcategories. It is also called a nested pie chart, concentric pie chart, or sunburst chart. This layered structure lets you display hierarchical data — like a market split by region and then by product — in one figure. The multi layer pie chart maker uses your already calculated category values as references for a conceptual draft.

For exact proportions, upload or paste a table with three columns: the parent category, the subcategory and its value. SciFig DataChart builds the nested pie chart from those numbers, with parents on the inner ring and subcategories on the outer ring, and exports it as PNG, PDF, EPS or TIFF. For an explanatory draft, give the multi layer pie chart maker your category totals, subdivisions, proportions and intended hierarchy. SciFig AI Illustration creates an explanatory concentric-ring visual from that input. Convert it to SVG to edit its paths and labels in Canvas.

Yes. Upload or paste a table with a category column and a value column, and SciFig DataChart draws an ordinary pie chart in which each slice is that category's share of the total. It handles up to 100 categories, sums rows that repeat a category, and can show percentages, raw values or both. Values must be zero or positive and cannot all be zero. Use the nested pie chart when each category also splits into subcategories.

A double pie chart usually places two separate pies side by side to compare two datasets or two time periods, while a nested pie chart stacks rings concentrically so an inner category expands into outer subcategories. Both are common ways to show more detail than a single pie. SciFig's multi layer pie chart maker supports both layouts, so you can build a double pie chart for before-and-after comparisons or a concentric pie chart for hierarchical breakdowns from the same interface.

A sunburst chart is a multi-layer pie chart designed for deep hierarchies — three or more levels of nested rings radiating outward. Use it when a single pie chart or even a two-ring nested pie chart cannot capture all the levels in your hierarchical data. A flat pie chart works best for a single set of proportions, while a sunburst chart or concentric pie chart shines when categories branch repeatedly. SciFig can render either, with labeled slices kept readable at every ring.

Yes. Clear labeling is essential in a multi-layer pie chart because each ring adds more slices. SciFig places labels inside or alongside each segment, with leader lines for thin slices, and lets you adjust font size and placement so the inner and outer rings stay legible. You can label by category name, percentage, raw value, or all three, which makes the exported figure ready for reports, slide decks, and publications.

Hierarchical or part-to-whole data works best in a multi-layer pie chart maker. Any dataset where a total splits into categories, and those categories split again into subcategories, maps naturally onto concentric rings — survey responses by group then answer, budgets by department then line item, or sales by region then product. If your data is flat with no sub-levels, a single pie chart or a double pie chart for two datasets is usually a better fit than a deeply nested multi layer pie chart. As a pie wheel maker for layered data, this pie wheel maker keeps every ring aligned with its parent category so the hierarchy stays readable.
