Pie charts show relationships between parts of a whole or percentages as pieces of a pie.
For example, readers can see the proportion of items within a budget or how much time and money are spent on each category or the breakdown of responses to a survey question. What are power users' primary concerns and issues, and how does this compare with environmental groups' concerns. Computer business software makes creating pie charts simple. Use one pie chart for each idea, such as a survey question, expenditures for a year, or water demands for a month in a given area. Divide a circle into pieces of pie.
