Yeah, I realised that part was a little messy :) I changed the logic of what I was doing several times while doing it, and ended up with things that way pretty much because it worked rather than because it was in the least bit graceful. I'd be interested to see what your version looks like (translation: it sounds simpler to look at your version than to work out the template matching and structure myself) - you can mail me off-list with a copy if that's OK. > Since we have folder and page nodes I multiplied the cx and > cy variables for folders by 4 to give more room for larger > sites. In doing so, I still get overlaps. Perhaps you have > plans for collision detection? :) Haha, actually one of the biggest things that put me off starting this was that I had no idea how to detect/prevent collisions (but that's also one of the biggest reasons I hate Visio - it's got a lot better in recent versions, but I still seem to end up spending more time tidying up lines than I do entering any kind of useful data). I was actually really surprised when I realised that the abstract-seeming code I'd entered managed to do a pretty good job of laying things out - mainly because of the way the angles are handled, and the fact that line length decreases the further you go from the "hub". But beyond that, I don't really know where I'd start. > Another feature might be to add interactivity where you can > click on a node to expand/collapse it (and center the node > clicked in the viewport). That's something I'd certainly considered, as well as adding drag functionality so that you can reposition nodes yourself. But it took enough for me to get to grips with the basic SVG - I want to take a deep breath before I start tackling scripting and DOM stuff as well. In the meantime, something else very simple which I'd meant to include but forgot was the ability to set a start page - for a very large site you could just do this several times, and so map the site in a series of smaller diagrams rather than one big messy one.
