UPDATE:
[3] shows, how all nodes <nodename> can automatically be linked to e.g.
http://en.wikipedia.org/wiki/<nodename> w/o codechanges on graphviz
software.
I recently came across Vic's extension package [1] which allows
visualisation by using the graphviz/dot package. Would like to ask,
whether this can be enabled on all wikis. I can only support this.
