A pie chart (or a circle chart) is a circular statistical graphic which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area ) is proportional to the quantity it represents.
Statistical graphics have been central to the development of science and date to the earliest attempts to analyse data.

The maximum number of slices that can be displayed is 30. Currently the default colors used for slices 15 onwards are all the same as the default color of slice 14. If the specified values add to 100 and |other= is set, the calculated percentage for that slice can sometimes turn out to be very strange (e.g., "1.4210854715202E-14%" instead of "0%")
The most common technique, first appearing in the 1850s, is to start with a proportional circle sized according to some total amount, and turn it into a pie chart to visualize the relative composition of the total, such as the percentage of a total population belonging to various ethnic groups.
