Convert the percentage values for each segment into degrees relative to the degrees in the circle. The title should be informative and rows and columns of tables or axes of graphs should be clearly labeled.
Pie charts these days are typically generated by computer software, as a result people forget that there is actually a little math involved.
How sure are you? What other assumptions are unfounded? One of the most popular types of charts is the pie chart. In addition to issues stemming from using too many categories, the biggest problem is getting the basic premise: Are the parts mutually exclusive?

Charts can be valuable when a need to represent numerical data would benefit communicating information visually. We can easily tell what the message is by simply looking at the accompanying percentages. A bar graph, rather than multiple pie graphs, is the better option if data need to be compared by more than one value.
Charts can be valuable when a need to represent numerical data would benefit communicating information visually. But used the right way, they are very powerful: Wikipedia has this beautiful specimen on the page on U.Constructing a circle graph/pie chart; Circle graphs/pie charts versus bar graphs; A circle graph/pie chart is a way of summarizing a set of categorical data or displaying the different values of a given variable (e.g., percentage distribution).This type of chart is a circle divided into a series of segments.
