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%.
Good to know
- Donut charts, like pie charts, are easy to create and understand.
- The donut chart, similar to the pie chart, offers a compact shape that makes it an excellent choice to fit into a dashboard and small screens.
- Take caution to not overload the chart with excessive categories resulting in confusing your audience with a crowded data in a compact chart. Alternatively use a treemap in the case of a large data set.
- Donut charts are limited to a single time frame, as it is not possible to show data trends overtime.
