Bubble Chart Creator/Circle Packing
$250-750 USD
Paid on delivery
I need a tool that will create vector-image Bubble Charts from a large list of data (n ≈ 1,000)
Take a look at [login to view URL] for an idea of what I mean.
The tool would need to:
* size the circles proportionally
* label the larger circles
* pack the circles using some kind of space-saving packing algorithm. It may make sense to pack them into a circle.
I note that Prefuse/Flare has some kind of capabilities in this space [login to view URL] - you might want to base your response on this, but I am v. open to suggestions.
This may be a web app, or a command-line app; I operate in an OS X environment.
Please include in your response to the bid:
* experience in this area
* examples of your work
* some initial ideas about how you might approach this problem.
Further visualisation libraries:
Protovis (JavaScript)
RubyVis (a port of Protovis)
I've also found this:

In light of these, I'll only consider lower-end bids.
