A pie chart effectively displays the proportion of the parts of a whole. For instance, a pie chart can visually display the percentage of men and women in Congress during a particular session.
Keep in mind that Pie Charts often work well for more general audiences. When preparing Pie Charts follow these guidelines:
- Labeled each slice of the pie chart
- Place the number or percentage under the corresponding label
- Avoid clutter by having no more than six slices within a pie
- Consider combining smaller groups to reduce the slices to six
