I'm preparing to launch a Wiki. Now, at the beginning, it is quite important for me to visualize how the the first pages I add are connected to each other. I found an extension called WikiViz that partially accomplishes what I am seeking. Here are a few images from Google Search:
Unfortunately this extension is no longer maintained and I doubt it plays nice with the newest version of MediaWiki.
Also, from what I can see, it uses a Java applet (very outdated). Or, it just generates images which aren't very useful: I'm trying to find an extension which actually uses Canvas & produces an interactive representation, at least with clickable links.
So, you Wiki gurus here, let the information flow :D.
