It took me less than 10 days (working less than 5 hours a day, so
roughly 40 hours) to make this beautiful map, with zoom, and
mouse-tracking tooltip with pie tweening

A version of this, together with other D3 creations, will soon be put
up on a site with about 6-7 million hits a day
Normally, without D3, I'd either have to settle with a terribly boring
solution or commit to 100 days to pull it off from scratch (perfection
has its cost)
So kudos to Mike and Jason who are making D3 richer and more
interesting each day
Thanks
