Summary | Discourse Graphviz provides the ability to add graphs to posts using the DOT language. |
 |
Install Guide | This plugin is bundled with Discourse core. There is no need to install the plugin separately. |
Features
This plugin uses the Viz.js library to render graphs.
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 Graphviz site for documentation and more examples.
Example
[graphviz engine=circo]
graph {
a -- b;
b -- c;
c -- d;
d -- e;
e -- g;
a -- g;
a -- c;
a -- d;
a -- e;
b -- d;
b -- e;
b -- g;
c -- e;
c -- g;
d -- g;
}
[/graphviz]
