Question

What is a pie chart?

Answer 1

A pie chart is a circular graphical representation used to display proportional relationships within a single data series. It divides a circle into sections, where the complete circle represents the cumulative grand total (100%), and each section represents a specific data category’s percentage contribution to that total. Because it lacks traditional horizontal and vertical axes, its layout is ideal for showing simple part-to-whole relationships, such as a company’s market share or annual budget distributions. To maintain visual clarity and ensure data labels remain legible for business analysis, it is best practice to restrict a pie chart to a maximum of five to seven data categories.
