A pie chart is a circular representation of data divided into sections by the drawing of radii.

A pie chart is a circular representation of data divided into sections by the drawing of radii.

  • Each section represents a percentage of some total.
  • The sum of the values of all sections is 100% of the total.
  • The sizes of the sections are directly proportional to the percentage of the total.
  • For example, if a given section represented 10% of the total value, the central angle of the section would be 36 degrees, or 10% of the total 360 degrees in the chart.
