A pie chart, also known as a circle graph, is a circular chart divided into segments by radii. Each segment illustrates the relative magnitudes or frequencies of data. Pie charts are a graphical method used in descriptive statistics to summarize qualitative data. The size of each slice in the pie is proportional to the number of data values within its corresponding class, making it easy to visualize proportions within a whole.12
