Other forms: pie charts

A pie chart is a circular graph that's divided into sections. By looking at a pie chart, you can quickly understand what proportion of the whole each section represents.

Pie charts are one way to look at statistical information — they're so simple that they can make it easier to comprehend data. Each section is shaped like a slice of pie, and together they make up a whole "pie." If one "slice" represents twelve percent of the whole, it will be narrower than the "slice" that represents twenty-five percent. The earliest such charts were first used in the 1800s, though they weren't named pie charts until the 1920s.
