A pie diagram or pie chart is an illustration to show how information breaks down into categories. There are examples in the related links. Basically each wedge in a circle is drawn in proportion to the amount of the whole it represents. For example if a pie chart was drawn for a collection of coins where half the coins were dimes and 1/4 of the coins were pennies and 1/4 of the coins were nickels, the pie would be cut in half and then one of the halves cut in half again. Each piece would represent one type of coin.
