We got this new mediawiki extension installed now. It needed a few perl modules to be installed via cpan, even though a few errors occured (that i reported to the author) it seems to work now.
You can create graphs like this:
source example:
<graph> [ S23 ] -> [ Neighbor1 ] [ S23 ] -> [ Neighbor2 ] [ S23 ] -> [ Neighbor3 ] </graph>
# 3 nodes
<graph>
[ S23 ] -> [ Neighbor1 ] [ S23 ] -> [ Neighbor2 ] [ S23 ] -> [ Neighbor3 ]
</graph>
# 4 nodes
<graph>
[ S23 ] -> [ Neighbor1 ] [ S23 ] -> [ Neighbor2 ] [ S23 ] -> [ Neighbor3 ] [ S23 ] -> [ Neighbor4 ]
</graph>
# 5 nodes
<graph>
[ S23 ] -> [ Neighbor1 ] [ S23 ] -> [ Neighbor2 ] [ S23 ] -> [ Neighbor3 ] [ S23 ] -> [ Neighbor4 ] [ S23 ] -> [ Neighbor5 ]
</graph>
