Nested Pie Chart Maker for Multi-Level & Layered Data

How the inner and outer rings line up

• Inner ring = categories: each parent slice is sized by the sum of its children, so the biggest category gets the widest wedge.
• Outer ring = subcategories: each child slice sits directly inside its parent's wedge, sized by its own value.
• Children of one parent share a color family — same hue, varied lightness — so you can read which subcategories belong together at a glance.
• Every angle is computed from a single total, which means the outer ring is guaranteed to add up to the inner ring exactly.

Two ways to make a multi-level pie chart here

• Precise mode: type your hierarchy as "Category, Subcategory, value" — one row per subcategory — and the tool groups by category, sizes both rings, and renders an exact nested pie as SVG. No dragging, no manual angles.
• AI illustration mode: describe the layered pie or sunburst you want in plain English and get a polished, presentation-ready graphic with themed colors and styling.
• Use precise mode when the proportions must be correct (reports, dashboards, homework); use AI mode when you want an on-brand visual for slides or social.

How to make a nested pie chart from your data

• List one row per subcategory in the format "Category, Subcategory, value" — for example "North America, Software, 40".
• Repeat the same category name on each of its rows; the tool groups them automatically into one inner-ring slice.
• The maker sums each category for the inner ring, sizes each subcategory for the outer ring, and aligns them so the layers match.
• Read the labels and legend, then download a clean, editable SVG to drop into a doc, slide, or worksheet.

When to use a multi-layer pie instead of a plain pie

Use a single pie when you only have one level of categories. Reach for a multi-layer pie chart when each slice naturally breaks down further — revenue by region and then by product, a budget by department and then by line item, traffic by channel and then by source. The nested layout keeps both levels in one figure and shows how the detail rolls up into the headline numbers. If your hierarchy is deeper than two levels, a sunburst-style illustration in AI mode reads better, while this precise renderer focuses on a clean, exact two-ring chart.

Reading and exporting your chart

The inner ring is labeled with category names; the outer ring labels each subcategory with its name and share where there is room, and a legend lists every subcategory and value. Because each ring is drawn from the same grand total, the percentages are consistent across layers. Export is a single click to an editable SVG — it stays crisp at any size and remains fully editable in vector software, so you can recolor, relabel, or resize it for a report, slide deck, or printed handout.
