Pie/Donut/Rose Chart

A pie chart is a type of visualization chart where the data is represented in circular format based on the categorical values, showcasing the part-to-whole contribution. Each slice of the chart represents individual categorical values. The arc length and the sector angle or area of each slice are directly proportional to the data. The slices in a pie chart add up to a total of 100% when viewed in percentage contribution. You can also showcase the data values on the pie chart without converting them to the percentage contribution. 

A donut chart is a type of pie chart with an inner radius. Compared to the pie chart, the donut chart showcases the data as arcs rather than slices. A rose chart, on the other hand, is another type of pie chart where all the area or radius of each slice is directly proportional to the data. 

Note

A pie, donut or rose chart are used to showcase the part to whole contribution.
