Problems with pie charts
Figure 11-10 shows a pie chart that was actually published by a state government
agency (the state will remain nameless). This chart has 18 slices and is pretty much
incomprehensible. If the goal was to present an accurate picture of how lottery funds
are disbursed, this chart fails miserably. Using a more appropriate chart type (see
Figure 11-11) converts this mess into a comprehensible and informative chart.
Figure 11-10: Violation: Inappropriate use of a pie chart. Guilty as charged.
Figure 11-11: Converting the pie chart to a bar chart makes it legible.
