What is a doughnut chart?
A doughnut chart is a pie chart with the center cut out. Functionally it's nearly identical to a pie chart, but the empty center can hold a total, key KPI, or label, which makes it a favorite for modern dashboards and slide decks.
Both show proportions. The doughnut packs more information per chart by using the center for context.
When to use it
Tips for making one well
1. Make use of the center
Place the total, a key metric, or a title in the center to add information density without crowding the chart itself.
2. Limit to about five items, same as a pie chart
If the slices get too thin they become unreadable. Group everything outside the top 5 into "Other."
3. Tune the ring thickness (cutout)
A thinner ring feels modern and refined. A thicker ring feels closer to a pie chart and emphasizes the data more strongly.
4. Pick a base color
Using a single base color with shades from light to dark gives a unified look (e.g., shades of blue). When you want to contrast items, use complementary colors.
