Here is an example of another java graph visualization, Tree by Texon. Quite pretty. Looks like they are using Processing for the smooth visuals.

tree accesses the source code of a webdomain through it’s url and transforms the syntactic structure of the website into a tree structure represented by an image. this image illustrates a tree with trunk, branches and ramifications. first each tree is initialized, than all html links are detected, chronologically saved and finally displayed.

the first tree corresponds to the domain; according to the syntax of the website each further tree that builds up represents a subpage including all existing elements. the color of these trees reflects the color values of the domain and its subpages.

The image below is the tree for this blog.

And this is the forest that appears after leaving it on long enough. (I am one of the trees on the right side)

The forest is built in real-time without any noticable refresh. Looks like an interesting art project, but there is no interactivity from what I can tell.

Why I blog this? Mark added a comment to my previous post about his visualization tool, MyDensity. I think he will enjoy the link - it seems to be fairly good example of a similar Java visualization. And to answer your question: I want it to be real-time, interactive, and visually pleasing. Basically, let me hunt with ease through the mass of data. And find subtle ways to give me more information on that data, such as using different colours, sizes, etc. But keep it simple :)
