Pie Chart

Also known as: circle chart

A pie chart is a circular graph that presents values as proportionate slices.

Before using a pie chart, consider using a bar chart or displaying numeric values directly for improved usability.

Pie charts are one of the most commonly used data visualizations but are often not the most effective way to compare data values. This is mainly due to the size of each slice and the number of data categories being represented. Pie charts can also be represented as a doughnut chart, which is generally better for users to compare the size of each slice or arc.
