I've worked with Storm for a while now, and I can say that having a quick visual on the makeup of your topologies is worth a lot. It's far easier to simply look at a graph, and see the connections between named nodes, than to browse through code. Invaluable when you're debugging a problem in production.

Along these lines, I think it would be a real asset to have a handful of useful visualizations in the UI.

One example would be circle packing, where the containing circles are topologies, and the inner circles are topology components. See http://mbostock.github.com/d3/talk/20111116/pack-hierarchy.html. The idea would be to write it flexibly, so that the size of each circle is given by a function over the topology and/or node. You could imagine representing such things as throughput, latency, (received - acked), (# of executors occupied), etc in this way. It would be a quick visual indicator of how your topologies are behaving.

Another example would be if you wanted a quick visual depiction of a topology -- you might use a graph, or a force-directed graph: http://mbostock.github.com/d3/talk/20111116/force-collapsible.html

Many more ideas here: https://github.com/mbostock/d3/wiki/Gallery

If you guys think any of these would be a valuable addition, I'd love to take a crack at it.

----------
nathanmarz: I would like to see a force-directed graph of each topology, with the size of the edges between nodes indicating the amount of throughput passing between them. Once we improve the metrics (notably issues #362 and #363) we can use color to indicate which components are likely bottlenecks in the topology.

It would be really cool if clicking on a node shows more detailed information (like a visualization of the incoming and outgoing throughput to each individual task in that component).

----------
gsilk: I'm on it.

----------
chenxiaozhao: i can‘t wait to see the force-directed graph ,which can show the incoming and outgoing throughput to each individual task in that component
