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.

Note:
  - 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
<verbatim>
<?plugin GraphViz [options...]
