Pie Charts
A pie chart (or a circle graph) is a circular chart divided into sections, showing the parts of a whole. It is named for its resemblance to a pie which has been sliced. While the pie chart is perhaps the most ubiquitous statistical chart in the business world and the mass media, it is rarely used in scientific or technical publications because it is difficult to compare different sections of a given pie chart. Pie charts can be an effective way of displaying information in some cases, in particular if the intent is to compare the size of a slice with the whole pie, rather than comparing the slices among them.
