I just want everything to keep popping up like in the spring graph, but I like the history pull-down box as well. Thanks Hi Mark,

I think that timelines (like Simile) and graph roaming applets (like a Prefuse graph instance or the Roamer component for Flex) will be available as interfaces for Freebase soon.

In the current version of SpringGraph, this feature is not implemented. However, since the source code for SpringGraph is available, you could attempt this modification yourself. The function SpringGraph.tick() gets called (using timers) periodically. This function calls forceDirectedLayout.tick(), to perform 1 round of calculations, and then calls invalidateDisplayList() to redraw everything in its new position. Roughly speaking, you would need modify this code to call forceDirectedLayout.tick() many times before calling invalidateDisplayList(). Ideally you would keep track of how much movement there is, and only do the redraw once the movement has gone below a certain limit.

If your 'node' xml elements look something like this: <node imageUrl="http://foo.com/abc.jpg"/>, then you can display the image by adding <mx:Image source="{data.data.@imageUrl}"/>to your itemRenderer.

I have a prototype of a network topology map based on SpringGraph (looks like Bruce Hopkins above is working on a similar project, so when/if you answer his question you will be answering it for me also :^) My question is related to the rendering. Is there a way to get the graph to "snap" to it's final layout? (or close to final layout) It would be nice to run the algorithm as fast as possible without the time it takes to show the bouncing, juggling nodes during the calculation process. Mark,

My question is related to the rendering. Is there a way to get the graph to “snap” to it’s final layout? (or close to final layout) It would be nice to run the algorithm as fast as possible without the time it takes to show the bouncing, juggling nodes during the calculation process.

I'm currently using SpringGraph in order to build a network topology map (in other words, show which servers, desktops, hubs, and proxies are communicating). Is there a way to annotate the lines between Items? That way, I can show the protocol name and data size. If not, then I guess that I could make the annotations an Item between the "real" Items that I want to display. Let me know your thoughts. Thanks Mark,

Please try out the thesaurus and let me know what you think. I looked at openkapow. It seems more elaborate than dappit. Thanks for the tip, maybe I'll try it for my next project.
