Graphviz allows you to build your own custom graphs within posts.
It utilizes viz.js to render graphs using one of Graphviz’s graphing languages, like DOT or Neato.
To embed a graph use [graphviz] [/graphviz]
bbcode. Optionally you can define layout engine attributes: [graphviz engine=neato]
. If engine is not defined, it defaults to the DOT engine.
See the documentation for a list of examples at GraphViz Pocket Reference and Deister Software to build your graph.
