Pie Chart

A pie chart, also known as a circle chart, is a circular statistical graphic divided into slices to illustrate proportional relationships between different parts of a whole. Each slice represents a category or segment of data, and its size (both in area and arc length) is directly proportional to the quantity it represents.

Description

  • Circle: The foundation of the chart, representing the “whole” being divided.
  • Slices: Each slice signifies a specific category or group within the data.
  • Size: The area of each slice is proportional to the value it represents, reflecting its contribution to the whole.
  • Labels: Typically added to identify each category and its corresponding percentage or value.
  • Colors: Different colors are often used to differentiate slices and enhance visual appeal.

When to use a Pie Chart

  • Show proportion of parts to a whole: Effectively visualize how different components contribute to a single entity.
  • Focus on composition: Highlight the relative size of each category, making it easy to see which category is largest or smallest.
  • Communicate simple comparisons: Convey basic comparisons between a few categories at a glance.
