### Features
This plugin uses the [Viz.js](https://github.com/mdaines/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](https://www.graphviz.org/documentation/) site for documentation and more examples.
### Example
```plaintext
[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]
```

🥳 This plugin is now bundled with Discourse core as part of [Bundling more popular plugins with Discourse core](https://meta.discourse.org/t/bundling-more-popular-plugins-with-discourse-core/373574). If you are self-hosting and use the plugin, you need to remove it from your `app.yml` before your next upgrade.

All these plugins will remain disabled by default, so this won’t have any visible impact on existing communities.
