Bar Graph

A bar graph is a form of graph which consists of a finite set of (usually) vertical bars whose length determines the statistic being communicated.

Pie Chart

A pie graph is a form of graph which consists of a circle divided into sectors whose areas represent the proportion of the corresponding statistic relative to the whole.


A pictograph is a variant of a bar graph whose bars consist of a number of icons or other pictorial symbols arranged in a (usually) line.
