Pie Chart Diagram Explanation

What is a Pie Chart?

A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. Each slice represents a specific category or data point and is proportional to the quantity it represents.

How to Interpret a Pie Chart?

To interpret a pie chart, you need to understand the following:

1. Categories:

Each slice of the pie represents a category or data point. The labels or legends alongside the chart indicate the meaning of each slice.

2. Proportions:

The size of each slice represents the proportion or percentage of the whole. The larger the slice, the bigger the proportion it represents.

3. Total:

The entire pie represents the total of all the categories or data points. The sum of all the proportions should equal 100%.
