Pie Chart Maker

A free pie chart maker with percent labels and a donut option

This pie chart maker draws a pie or donut chart from a small table of names and numbers. Type the values, or paste two columns from Excel or Google Sheets, and every slice is sized, coloured and labelled for you. Use it for a household budget, a class survey, a market-share slide or a science project: anything where the parts add up to one whole.

You can show percentages, the values themselves or both, put the labels outside with leader lines or inside the slices, group the small slices under “Other”, rotate the start angle, and turn the chart into a donut with the total in the middle. Download a sharp PNG, an editable SVG or a vector PDF, or print it. Nothing is uploaded: the chart is drawn in your browser.

How to use the Pie Chart Maker

1. Edit the example table (a pocket-money budget in ₹) or press Start blank. One row is one slice: a name and a positive number.
2. Paste from a spreadsheet into any cell, or open Paste or open a CSV and drop in two columns. Extra columns are ignored.
3. Choose Percent, Value or Value and percent for the slice labels, and set a prefix such as ₹ or $ for the values.
4. Tick Donut for a ring, or Group small slices as Other and set the percentage below which slices are merged.
5. Give the chart a title and download the PNG, SVG or PDF. “Data as CSV” saves the table for later.

How the slices are calculated

Each slice’s share is its value divided by the total of all positive values, and its angle is that share times 360 degrees. The first slice starts at 12 o’clock and slices run clockwise; the start-angle slider rotates the whole chart. Percentages are rounded individually for display, so rounded labels can add up to 99% or 101%: with Automatic decimals the tool shows one decimal place (30%, 7.5%), and you can set 0, 1 or 2 decimals.

A pie chart can only show parts of a positive total, so rows with a zero or negative value are left out and the page tells you how many. Blank rows are ignored. The arcs are drawn as exact curves, so the PDF stays sharp at any size.

Making a pie chart people can read

• Keep to about five to seven slices. If there are more, use Group small slices as Other or switch to a sorted bar graph, which is easier to compare.
• Sort largest first (or start the biggest slice at 12 o’clock with the start angle) so the eye finds the main story first.
• Use outside labels with names when slices have different colours that might be confused; use inside percentages with a legend for a cleaner look on slides.
• Pies suit shares of one whole. To show change over time use a line graph; to learn what fractions and percentages mean, try the fraction visualizer.
• For black-and-white printing choose the greys palette; the white gaps between slices keep them distinct.
