Pie Chart Maker

Make a Pie Chart for a School Project

Class survey, science fair data, a book report broken into chapters: if the assignment says "make a graph", a pie chart is usually the friendliest option, and this tool is built to make one in a couple of minutes.

Type category names and numbers into the table, and the chart draws itself while you type. There is nothing to install and no account to create, so it works on a school Chromebook, a library computer, or a phone. When it looks right, download it as an image for a slideshow or print it for the poster board.

The colors are the fun part. Twenty palettes range from serious to playful, or click any slice to give it exactly the color you want.

When to use it

  • Class surveys: favorite season, pets at home, transport to school
  • Science fair results with a handful of categories
  • Math homework about fractions, percentages, and angles
  • History or geography breakdowns, like land use or population groups

Tips for a better chart

  • Collect data with a tally chart first, then type the totals in.
  • Give the chart a title that says what was measured and who was asked.
  • Show percentage labels. Teachers usually want the math visible.
  • Print in black and white? Choose the print-friendly palette so slices stay distinguishable without color.

Frequently asked questions

Do I need an account to make a chart?

No. The tool is free and works without signing up. Open the page, type your data, download your chart.

Does it work on a school Chromebook or iPad?

Yes. Everything runs in the web browser, with nothing to install. It works on Chromebooks, tablets, phones, and lab computers.

How do pie chart angles relate to percentages?

A full circle is 360 degrees, so each percent of the total is 3.6 degrees. A slice worth 25 percent spans 90 degrees. This tool does the math for you, but showing it is a nice touch in a math project.

Can I print my chart?

Yes. Download it as a PNG or PDF and print it. The print-friendly palette keeps slices tellable-apart even on a black and white printer.
