Frequently asked questions

Should percentages add up to 100?

They do not have to — Chart.js renders raw values as proportions of the total.

What is Pie Chart Maker?

A Pie Chart Maker is a tool that converts two-column CSV data into a pie chart in the browser. It divides a circle into proportional slices, one per row, and assigns each slice a colour automatically. The resulting chart can be exported as a PNG image, with all rendering performed client-side and no data uploaded to a server.
