+The `graph` directive is supplied by the [[!iki plugins/graphviz desc=graphviz]] plugin.
+This directive allows embedding [graphviz]( graphs in a
+page. Example usage:
+ \[[!graph src="a -> b -> c; a -> c;"]]
+Note that graphs will only show up in previews if your browser has
+[[!wikipedia data: URI]] support, or if the same graph already exists on that
+The `graph` directive supports the following parameters:
+- `src` - The graphviz source to render.
+- `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.
