version 2

The GraphViz plugin passes all its arguments to the grapviz dot binary and displays the result as cached image (PNG, GIF, SVG) or imagemap. See http://www.graphviz.org/Documentation.php, esp. http://www.graphviz.org/doc/info/lang.html for the dot language specs.

Notes

We support all image types supported by GD so far, PNG most likely.
On imgtype = imap, cpamx, ismap, cmap an additional mapfile will be produced.

Usage

<<GraphViz [options...]
   multiline dot script ...
>>

Arguments

Argument	Description	Default value
imgtype	Image type	png
alt	Image alternate text
pages	<! plugin-list support !> encoded as pagename = [ URL = url ]
exclude	Exclude pages
help	Display argument help

Example

<<GraphViz
digraph automata_0 {
        size ="8.5, 11";
        node  [ shape  = circle];
        0 [ style = filled, color=lightgrey ];
        2 [ shape = doublecircle ];
        0 -> 2 [ label = "a " ];
        0 -> 1 [ label = "other " ];
        1 -> 2 [ label = "a " ];
        1 -> 1 [ label = "other " ];
        2 -> 2 [ label = "a " ];
        2 -> 1 [ label = "other " ];
        "Machine: a" [ shape = plaintext ];
}
