What is the primary purpose of a circle graph (pie chart)?

A circle graph, or pie chart, is used to illustrate the composition of a whole. Each slice represents a part of the total, and the size of the slice reflects how large that part is in relation to everything else. This makes it easy to see which categories dominate the whole and how the total is distributed among them. It’s not meant for displaying a data table, since it visualizes proportions rather than presenting data in rows and columns. It also isn’t ideal for showing time-series trends, which are better captured by line graphs that track changes over time. And it doesn’t measure means or averages; that kind of comparison is better shown with bar charts or similar plots.
