The plugin uses the wonderful nomnoml package for converting code to SVG, so the syntax for using this plugin is what nomnoml supports.

Want more? Here's a diagram with links to internal documents:

[You are here] -> [mega://packages/megadoc-html-dot/README.md as "Back to the top"]

Installation

npm install megadoc megadoc-html-dot

Add it to your list of plugins:

// @file: megadoc.conf.js
exports.serializer = [ 'megadoc-html-serializer', {
  plugins: [ 'megadoc-html-dot', {
    // config here
  }]
}];

Usage

Inside your Markdown blocks, name your fenced code blocks with the dot language and type away!

```dot
[A] -> [B]
[C] -> [B]
```

Or, use UML:

```dot
[<frame>My Model|
  [A] -> [B]
  [C] -> [B]
]
```

Configuration

At this moment, the plugin doesn't really accept any config. By default, we override the following "directives" to make the graphs more in-line with megadoc's color scheme:

• #fontSize: 10
• #font: Monospace
• #lineWidth: 1
• #fill: #eaeaea
• #stroke: #404244

You can still override this on a per-graph basis in your dot` blocks.

Linking to internal documents

It's not possible to link using the regular linking schemes inside your diagrams, instead you must use a special syntax that looks something like this:

[mega://my-link]

And if you want to customize the text:

[mega://my-link as "My Custom Text"]

It's totally possible to frame it:

[Foo | mega://my-link]
[Foo | mega://my-link as "My Custom Text"]

Which will look something like this:

[Foo | mega://packages/megadoc-html-dot/README.md as "My Custom Text"]

Credits

Big thanks to nomnoml and dagre for making this possible. Such beautiful work.
