This is an example of a federal budget pie chart, as you can see from the data percentages, there are several large and little slices in the chart. The entire circle (or pie) symbolizes the total federal budget, and each slice separates the data segments according to the amount of federal spending allocated to the federal sector. Because a pie chart can't compare subclasses or two data sets, each slice includes both required and discretionary spending percentages. The reader can easily grasp federal spending without relying on numerical statistics.
