In a pie chart, the arc length of each slice (and consequently its central angle and area) is proportional to the quantity it represents.
Let p be an interior point of the disk, and let n be a multiple of 4 that is greater than or equal to 8. Form n sectors of the disk with equal angles by choosing an arbitrary line through p, rotating the line n / 2 − 1 times by an angle of 2 π / n radians, and slicing the disk on each of the resulting n / 2 lines.

A perfect rectangle of order 9 Lowest-order perfect squared square (1) and the three smallest perfect squared squares (2–4) – all are simple squared squares. A rectangle tiled by squares, rectangles, or triangles is said to be a "squared", "rectangled", or "triangulated" (or "triangled") rectangle respectively.
{} is an experimental graph-drawing template that produces a pie chart 200 pixels wide in the article. When making a pie chart, ensure that the segments are ordered by size (largest to smallest) and in a clockwise direction. [clarification needed] Setting the other parameter to yes will pad the chart so that the values total to 100.
