What is a Donut Chart?

A donut chart is a circular chart with a hollow center that displays proportional data as slices of a ring. Like a pie chart, each slice represents a share of the whole, but the open center gives you space to highlight a total, KPI, or key label. Donut charts work best with 2–6 categories and are ideal when you want to show part-to-whole relationships in a clean, visually distinct format.

Key Features

Adjustable Inner Radius

Control how thick or thin the ring appears to balance readability and visual weight.

Flexible Label Positions

Place labels inside the ring, outside with leader lines, or hide them entirely for a clean look.

Label Content Options

Display slice names, raw values, percentages, or combinations like name + percent.

Start & End Angle Control

Rotate the chart or clip it to a partial arc to draw attention to specific segments.

Padding Angle & Corner Radius

Add spacing between slices and round their ends for a polished, modern appearance.

Legend Positioning

Place the legend at the top, bottom, left, or right to fit your layout.

When to Use

  • You have 2–6 categories that sum to a meaningful whole
  • You want to show part-to-whole relationships at a glance
  • You need the center to highlight a total, KPI, or headline number
  • Relative size matters more than precise values
  • Your audience expects a circular format for proportional data
  • You're showing composition rather than change over time

Common Mistakes

  • Using more than 6 slices — small slivers become impossible to compare
  • Including an 'Other' slice that is larger than most named categories
  • Starting the chart at an unusual angle, making clockwise reading awkward
  • Assigning similar colors to adjacent slices, reducing visual distinction
  • Leaving the center empty when a total or KPI would add clear value
  • Choosing a donut when a bar chart would make precise comparisons easier
