Donut charts, like pie charts, are used to compare categorical data.
The demo below displays the car's registration by February 2020 in Norway; the demo is a comparison of the data of electric cars, hybrids, diesel, and petrol cars.
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/or small screens.
- Take caution to not overload the chart with excessive categories. This could result in confusion among the audience due to the crowded data in a compact chart. Alternatively, one can use a treemap to visualize a large data set.
- Donut charts are limited to a single time frame, as it is not possible to show data trends overtime.
