What Is a Donut Chart?

A donut chart is a circular visual similar to a pie chart but with an empty center. It is used to show parts of a whole, multi layer data, or relationships between categories. This format is popular in presentations, dashboards, and reports. With a donut chart maker, you can prepare your categories and values clearly before creating the final donut pie chart.
