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:graphordigraph. Defaults todigraph.prog- The graphviz program to render with:dot,neato,fdp,twopi, orcirco. Defaults todot.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.
