Pie Chart
Definition
A pie chart is a circular graph divided into sectors, where each sector represents a category and its size corresponds to the proportion or percentage of data values in that category.
Analogy
Think of a pie chart as if you were dividing up slices from an actual pie. Each slice represents a different category, and its size reflects how much of the whole pie (or dataset) it represents.
Related terms
Sector Angle: The sector angle refers to the angle formed by each sector in a pie chart. It can be calculated by multiplying the proportion/percentage represented by each sector by 360 degrees.
Data Labels: Data labels are text labels placed inside or outside each sector in a pie chart, indicating either the exact value or percentage represented by that category.
Exploded Pie Chart: An exploded pie chart is when one or more sectors are separated from the rest of the chart for emphasis. It helps highlight specific categories within the dataset.
