Help:Graph

The Graph software extension allows the creation of graphs by use of the  parser tag. The graphs include bar charts, pie charts, line charts, area charts, scatter plots, tag clouds, tree maps, and political maps.

Bar/line/area charts can be easily created by using Template:Graph:Chart; the documentation for this template explains its functions and use in extreme detail.

Since 2015, interactive graphs are available: mw:Extension:Graph/Interactive Graph Tutorial
