Installing the Graphviz Plugin

By installing this plugin you will be able to create graphs directly in Dokuwiki. You will have to learn the DOT Language, but it's fairly simple. Read more about Graphviz here.

Install graphviz, imagemagick, and some fonts:

aptitude install graphviz imagemagick ttf-freefont ttf-bitstream-vera

• Login to Dokuwiki under an administrative account and go to Admin→Plugins Or something like that.
• Make sure <wikidir>/lib/plugins is writable by www-data.
• Paste http://danjer.doudouke.org/graphviz.zip into the field and download the plugin. Dokuwiki will unzip and install it for you. There is no configuration.
• Lock down <wikidir>/lib/plugins after this (group, world: read-only).
• Test it out:

<graphviz>
digraph {
A->B;
B->C;
A->C;
}
</graphviz>

<graphviz> digraph { A→B; B→C; A→C; } </graphviz>

See http://www.graphviz.org/Gallery.php as well.
