Pie Chart Generator – Show How a Whole Splits into Parts
The Pie Chart Generator turns a list of categories and values into a clean pie or donut chart, ready for a report, slide, or social post. It answers one question at a glance: how big is each part relative to the whole? A monthly budget, a poll result, market share, time spent per project — if the values add up to a meaningful total, this is the chart for it. Everything runs live in your browser with no sign-up and no watermark.
Enter Data Your Way
Type categories and values into the editable table, or copy two columns from Excel or Google Sheets and drop them into the Paste tab — a header row is detected automatically. The Upload CSV tab accepts files in the same shape:
Category,Amount
Rent,1200
Groceries,450
Transport,200Only positive numbers become slices; zeros, negatives, and text are skipped, so a stray row never breaks the chart.
Pie or Donut, Labeled Your Way
Switch between a classic pie and a modern donut with one click — both encode identical data, but the donut's open center reads a little easier and leaves room for the eye to rest. Choose what each slice says about itself: name and percent (the default), percent only, the raw value, or nothing at all — the hover tooltip always carries the exact number either way, and a legend below the title lists every slice with its color.
Readable by Design
Pie charts fail when they have too many slivers, so the generator protects readability automatically. Slice colors come from a colorblind-safe palette with eight distinguishable hues, and when your data has more categories than that, the smallest ones are grouped into a neutral gray “Other” slice (you can switch this off if you'd rather keep every sliver). A sort largest-first option arranges slices clockwise by size, which most readers find easiest to scan. Slices are separated by a thin gap in the background color, and the whole chart adapts to light and dark mode with colors tuned for each background.
Export and Share
The export bar captures the framed chart — title, legend, and plot — exactly as shown. Download a sharp 2×-resolution PNG for documents and presentations, a scalable SVG for design tools, copy the image straight to your clipboard, or download the underlying data as CSV.
When Not to Use a Pie
A pie compares parts to the whole — not parts to each other. If your categories are close in size, if there are many of them, or if the values don't sum to a meaningful total (like average temperatures), readers will struggle to judge the differences. In those cases switch to the Bar Chart Generator, where length along a common baseline makes small differences obvious.
