Why are 3D pie charts misleading?

The usage of percentages as labels on a pie chart can be misleading when the sample size is small. Making a pie chart 3D or adding a slant will make interpretation difficult due to distorted effect of perspective. Bar-charted pie graphs in which the height of the slices is varied may confuse the reader.

What can I use instead of a pie chart?

Stacked Bar Charts are the closest linear equivalent to Pie Charts, in terms of both one-to-one mapping and layout. They may be the best alternatives to Pie charts. A single-series Pie chart with N slices is actually equivalent with N series of Full 100% Stacked Bars, each with one single value.

When should you not use a pie chart?
