A pie chart is a circular object that represents data in terms of what portion, or piece, of the whole it encompasses. This type of visual aid is often used to represent polling results, budget information, or any other collection of data where you want the viewer to have a clear idea of how each individual slice fits into the big picture.
There are several versions of pie charts that can be created in Microsoft Excel 2007. Depending on your data and what you want to stress with that data, each type of pie chart has its own distinct advantages. In this series, we’ll look at how the same set of data can be represented in several ways through the use of various types of pie charts.
