Pie Charts

Pie Chart Example

Pie charts are data visualizations best used for when you want to show a one-to-many comparison between the different data sets being represented. They can illustrate relative magnitudes, frequencies, or percentages.

Pie charts are one of many types of data visualizations used to organize and present data in a way the audience can understand and take action on. To ensure visualizations have real business value, it’s important to know which types of visualizations are best suited for a given data set.

Alternative visual styles to traditional pie charts include an exploded pie wedge chart, for when you want to emphasize important data, and a donut pie chart (a pie chart with a hole in the middle), if you want to insert a design element in the center to support the information being displayed.
