Pie chart is an extensively used graphical technique for presenting relative frequencies related with the observed values of the categorical variable. The chart comprises of a circle subdivided into the sectors whose sizes are proportional to the quantities (generally percentages) they represent.

An instance is shown in the figure. These types of displays are popular in the media but have small relevance for the serious scientific work when other graphics are usually far more useful.
