Really nice demo.
But there's one semi-unrelated thing I noticed (disclaimer: yeah, I don't like Flash either, but): This demo, with a handful of animated bezier curves drove one CPU to 40% (using Chrome on a Mac). And this is something that I repeatedly encountered with graphics rendering done in Javascript. The whole "less flash"="less cpu-usage with animation"-thing might be a little premature.
I find that simple SVG animations frequently push up the CPU, but Canvas can do much better. I wouldn't be surprised if this same demo used only 2-3% of your CPU in Canvas.
WebGL should deliver another order-of-magnitude speed increase, but I'm holding off for another 6 months or so for things to stabilize before diving into the 3d context.
nice demo, clicking on stuff led to http://circos.ca/ which is also very awesome :)
Cute. I found it a bit annoying that P1 couldn't be dragged left, but the demo was otherwise very cool.
P1 is free to move, but is already at the left-most side of it's sandbox. To get P1 further left relative to P0, you'll have to move P0 to the right.
Yep, I realize that, but the first thing I wanted to do was drag P1 left and that's impossible.
Why would you use a data vis lib for drawing a couple of lines? Wouldn't raphael.js be more appropriate? (i.e. efficient)
