How do you make a misleading pie chart?

You can do it in several ways. One is to pick your colors so that you emphasize certain parts of the pie. Brighter colors or ones that are darker than the neighbor colors stand out more. This can make the reader emphasize certain parts of the chart when they otherwise would not. Next, pie charts are often presented in 3 d relief. If you point the top of the chart away from the reader you can distort the perception.
