Really interesting way to present lots of data.
(pixelmap with magnifier)
Useful D3 stuff from Susie Lu
like a really awesome Annotation Plugin
Check out Topi Tjukanov's spatial visualisations too
Jim Vallandingham's site has some unique examples as well
And here are two sites to find more d3 examples
I also found some good d3 twitter feeds worth mentioning
Okay. I love data no matter how it looks..
but this is really beautiful data visualization
You can see the visualization presentation for yourself on youtube
Or just go the the pages of the creaters here:
