A pie chart is a circular chart that uses "slices" to represent the relative sizes of data. It is an effective way to compare data, information, and statistics in an easy-to-read format, with varying slice sizes indicating the proportion of each data element.
Pie charts are best suited for displaying data with six or fewer categories. When there are too many categories, it becomes challenging for the eye to distinguish between the relative sizes of the slices, making the chart difficult to interpret. Used appropriately, pie charts are excellent for illustrating topics such as expenses and profits, population segments, or survey results.
Pie charts can be used in various situations, including:
Add just the right amount of color. Shade the different pie slices so they transition from dark to light tones as you move from the first to the last slice.
Ensure your slices are distinct and not too similar in size. Consider experimenting with different configurations and design elements to enhance clarity and visual appeal.
Adding a legend reduces the amount of text within the pie chart and provides an "at-a-glance" reference, making the graphic easier to understand.
