hi!
In de: we have a lot of articles on graph theory missing example images. Graphs are also useful in other articles to visualize information. Editing images of graphs with your favorite program and format is a consumption of time and nobody can easily alter my images. We do have <math> and <hiero>-section. I'd like editable graphs with <graph>...</graph>.
We could easily use the DOT-syntax and [http://www.research.att.com/sw/tools/graphviz/ graphviz] to create PNG-images or SVG. It's damn powerful and not that complicated!
Greetings, Jakob

I really really hate graphviz. It rarely if ever produces any usable output. The graph is *always* either far too big, or the nodes are too small to read.
I've seen much better auto-generated graphs, but unfortunately not from open-source software.

I've never used it before, but the sample graphs on the above-linked website are mostly illegible.

Last time I used graphviz, it didn't do any kind of anti-aliasing, so the graphs quickly became ugly/illegible if you tried cramming too much information in too small a space. Where there is enough space to render things comfortably, graphviz does quite nicely. For instance, take a look at:
http://www.research.att.com/sw/tools/graphviz/examples/directed/fsm.gif http://www.research.att.com/sw/tools/graphviz/examples/directed/datastruct.g... http://www.research.att.com/sw/tools/graphviz/examples/directed/world.gif http://www.research.att.com/sw/tools/graphviz/examples/undirected/process.gi...
I think my solution for bigger graphs at the time was to render them in graphviz, and then resize using ImageMagick. A bicubic resize manages to keep the graphs at least decent - nearest neighbor and bilinear make things *really* ugly (lines will no longer be, er, lines).
Cheers, Ivan

I just found this old thread in the Newsgroup.
My question is: Has this graph drawing plugin actually been coded or is it still nothing but an idea?
cheers, Ingmar

We're currently finishing up support for GnuPlot at wikisophia.org (see "Additional Features"); and once we've achieved XML-like syntax, we should be able to integrate it with Mediawiki.
Best, Peter
