Creating Pie of Pie and Bar of Pie charts

Pie charts are excellent for displaying data points (data points: Individual values plotted in a chart and represented by bars, columns, lines, pie or doughnut slices, dots, and various other shapes called data markers. Data markers of the same color constitute a data series.) as a percentage of the whole. However, when several data points each amount to less than 5 percent of the pie, it becomes hard to distinguish the slices. For example, a pie chart of the following sales data contains three slices that fall below 5%.
