Pie Chart

Also known as Circle Graph

1. What is a Pie chart?

A pie chart breaks down proportions and percentages between categories by dividing a circle into proportional segments. Each segment size represents a proportion of each category, while the entire circle represents the total value of all the data summing up 100%.

When to use a Pie Chart?

A pie chart is ideal in the case when you want to show the breakdown of data into its segments. Pie Charts is helpful in the following scenarios:

  • Comparison between each segment of data.

  • When you have only ONE data series.

  • Each category represents the part of the entire pie.

  • The segments are of comparable sizes so that the value of one segment does not dwarf the values of other segments.
