A chart made by plotting the numeric values of a set of quantities as a set of adjacent circular wedges with arc lengths proportional to the total amount. All wedges taken together comprise an entire disk. One or more segments are slightly separated from the disk center for emphasis in a so-called "exploded" pie chart. Pie charts are implemented in the Wolfram Language as PieChart[data].
