In general, pie charts are best used when your data implicitly carries a part/whole
relationship (like in the case of many percentages) and when the point of the data is
to illustrate the "make-up" of a single group. This is because any given group will
require its own chart. If you have three "groups," then it might be advantageous to
consider a bar graph. To illustrate this point, let's plot all the percentages from all
three companies, which necessitated three pie charts, on one bar graph.

Pie charts are also unable to represent data that does not implicitly carry a
part/whole relationship. For example, you want to demonstrate the average cost of
buying a home in the U.S. over the course of the 1980s.
