Ideas anyone? [Jan. 25th, 2003|12:00 pm]

Using a free graphing library, I threw together a quick and dirty program for visualising your friends neighbourhood. It screen-scrapes userinfo pages to grab lists of friends, and their friends, and then draws them. It's very much a one-hour prototype right now, I wanted to see how it'd look before investing any real time on things like interface or navigation.

I got this far into the prototype, and sort of lost faith because the whole thing is just too dense to get any real information out of. I could make it a little more readable by changing the colour/opacity/z-order of the nodes based on how well-linked they are, but I have a feeling I need something more before this can be a worthwhile toy.

It's fun, though.

Any ideas on how the data could be better visualised? I thought at first that hiding "unimportant" nodes would help, but the outliers (nodes with a single link to them) are the only things that prevent the graph from totally collapsing in on itself. It's not the edges that are the problem, it's the big, honking mess in the middle.

You may try to do a repelling algorthm(where labels try to repel each other and repel a user defined boundry).


Another possiblility is to do a tree structure, that expands and collapses...

such as:

  *       *
   \     /
    \   / 
     \ / 

  *      -*-
   \     /
    \   / 
     \ / 

Sorry my ANSI isn't that good...

Then you can balance this tree, so that the middle has less nodes coming off of it then the edges,(which has more room to expand).


Another way you may attempt this is done on this web site:

Enter and view a chart that is somewhat simular to what your doing...
hope this helps
