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;"]]
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|ikiwiki/wikilink]] 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.
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.
