:discourse2: Summary Discourse Graphviz provides the ability to add graphs to posts using the DOT language.
:open_book: 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]
