ikiwiki/ ikiwiki/ directive/ graph

The `graph` directive is supplied by the graphviz plugin.

This directive allows embedding graphviz graphs in a page. Example usage:

    [[!graph  src="a -> b -> c; a -> c;"]]

Nodes on the graph can link to external urls using regular graphviz syntax, and a clickable imagemap will be created. As a special extension for ikiwiki, WikiLinks can also be used. For example:

    [[!graph  src="""
    google [ href="http://google.com/" ]
    sandbox [ href=[[SandBox]] ]
    help [ href=[[ikiwiki/formatting]] ]
    newpage [ href=[[NewPage]] ]

    google -> sandbox -> help -> newpage -> help -> google;
    """]]

The `graph` directive supports the following parameters:

- `src` - The graphviz source to render.
- `file` - A file in the wiki containing the graphviz source.
- `type` - The type of graph to render: `graph` or `digraph`. Defaults to `digraph`.
- `prog` - The graphviz program to render with: `dot`, `neato`, `fdp`, `twopi`, or `circo`. Defaults to `dot`.
- `height`, `width` - Limit the size of the graph to a given height and width, in inches. You must specify both to limit the size; otherwise, graphviz will choose a size, without any limit.
