Donut charts, like pie charts, are used to visualize composition of categorical data.

The demo below displays the composition of the air. The air is a combination of different gases. From the chart, it is clear with 78% that nitrogen is the most abundant gas in the air, followed by oxygen with 20.9%.

Nice to know
