Pie Chart

Definition of Pie Chart

A pie chart is a circular data visualization that represents data as slices of a pie. Each slice corresponds to a category or variable, and its size is proportional to the value or proportion it represents. Pie charts are commonly used to display proportions, compare categories, and showcase the relative contributions of different elements within a dataset.

Pie charts are important in data visualization as they provide a visually appealing and intuitive representation of proportions and percentages. They allow for quick understanding of the distribution of data and enable comparisons between categories or variables.
