Pie charts are used to compare categorical data.
The demo below visualizes the earth's water supply by comparing salt water, ice, and freshwater.
Good to know
- Pie charts, similar to donut charts, are easy to create and understand.
- The pie chart, like the donut 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 otherwise the result confuses the audience with a crowded data in a compact chart. Alternatively, use a treemap in the case of a large data set.
- Pie charts are limited to a single time frame, as it is not possible to show data trends overtime.
