Pie charts

edit

You can add a pie chart with a call to this template. This template uses the Vega version 2 JSON specification. An older template {{Pie chart}} is based on CSS rendering. The template GraphChart allows adding of map, line, bar and area charts, as well as stacked line, stacked bar and stacked area charts, but no pie charts. The template GraphChart also uses Vega version 2 and uses Module:Graph with Scribunto/Lua programming. This Template:Graph:PieChart doesn't use Lua.

Parameters

edit
  • radius specifies the radius of the pie chart in pixels, default is 100
