Build a Donut Chart When You Need One Big Number and a Share Breakdown

A donut chart is useful when the audience should understand two things quickly: the total in the middle and how that total is divided around the ring. That makes it a practical choice for traffic-source share, budget allocation, ticket categories, survey splits, or any summary where one headline number matters as much as the composition behind it.

A quick tutorial workflow

• Start with a short list of categories and values that truly add up to the story you want to tell.
• Keep the number of slices small enough that each segment remains distinguishable at a glance.
• Use the center space for the main total or label that people should remember first.
• Preview the chart and check whether the legend, labels, and color contrast still work when the chart is viewed at slide or document size.
• Export it only after the breakdown reads clearly without a long verbal explanation.

When a donut chart works better than a bar chart

Use a donut chart when the core question is composition, not exact ranking. If the audience must compare categories precisely, a bar chart is usually clearer. But when the message is mostly how the whole is divided, the donut can communicate faster.

What makes the chart easier to read

• A limited number of categories.
• Distinct colors with enough contrast between adjacent slices.
• A center label that names the total or metric clearly.
• Labels that stay short instead of explaining the whole chart inside the legend.
