This applet allows the user to make pie charts. A pie chart is a graphical way to organize data.
All pie charts compare parts of a whole.
For example, a pie chart for the time you spend at school would compare the amount of time you spend in each class and at lunch. A pie chart uses percentages to compare the information. Percentages are used because it is the easiest way to represent a whole. So, you spend seven hours at school and 55minutes of that time is spent eating lunch. Thirteen percent of your school day is spent eating lunch.
