Pie graphs are good for showing portions of the whole. Like if you wanted to show expenditures of a business as percentages (or portions) of the whole. So there may be a section of the 'pie' for labor, a section for rent, a section for utilities, etc.
This may be more useful than looking at raw dollars, especially if comparing two companies in the same industry, but of different sizes. One might have 2 million dollars in expenses for the year, while the other has $500,000 a year, but they may have similar proportions. Or you may find out that one company has a bigger portion spent on rent, than the other, for example.
