# 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.
