How to make a pie chart

  1. 1

    Add categories and values

    Enter data manually, paste a two-column table, or upload a CSV or Excel file.

  2. 2

    Confirm the value series

    For tables with several numeric columns, open Customize and select the series that represents the whole.

  3. 3

    Customize and export

    Adjust the title, legend, colors, and labels, then download the chart as PNG or SVG.

What is a pie chart?

A pie chart divides one total into proportional slices. Each category supplies a label, and its numeric value determines its share of the complete circle.

This pie graph maker calculates percentages automatically from the selected value column. It works best with a small number of nonnegative categories whose values represent parts of one whole.

Example pie chart data

The category column supplies slice labels, while the Value column produces shares of 40%, 30%, 20%, and 10%.

Pie Chart vs Bar Graph

Both charts compare categories, but a pie chart emphasizes share of a whole while a bar graph supports more precise comparisons.

Use a pie chart

Use a pie chart when one numeric series forms a meaningful whole and a small number of slices makes the largest and smallest shares easy to recognize.

Use a bar graph

Use a bar graph for many categories, close values, negative numbers, or comparisons that do not add up to a meaningful total.

When to use a pie chart

Pie charts are most effective when a small set of categories represents every part of one meaningful total.

Show composition

Explain how products, channels, expenses, or responses contribute to a complete total.

Highlight dominant shares

Make a clearly largest or smallest category immediately recognizable.

Present simple percentages

Communicate a short breakdown when approximate proportions matter more than fine differences.

Readable legends

Use category names in a scrollable legend that remains usable with longer labels.

Compatibility guidance

Explain invalid values and suggest Scatter or Bar when another chart better fits the data.

CSV and Excel import

Upload CSV or XLSX files, or paste directly from Excel and Google Sheets.

Pie chart maker FAQ

Answers to common questions about percentages, value series, and compatible pie chart data.

Is this pie chart maker free?

Yes. This free pie chart maker works without signup and exports clean charts without a watermark.

How should I arrange pie chart data?

Place slice names in the first category column and nonnegative numbers in one value column. The online pie chart maker calculates each percentage from the total.

How are pie chart percentages calculated?

Percentages are calculated automatically by dividing each slice value by the sum of all selected values. Tooltips retain the original value and its share.

What if my table has multiple numeric columns?

Open Customize and deliberately choose one numeric column under Pie value series. A pie chart represents one total at a time.

What data is incompatible with a pie chart?

Negative values and all-zero totals cannot form valid slices, so the pie chart generator explains which values need correction. Numeric X/Y-only data is redirected to Scatter instead.
