This visualization, while technically impressive, could use a little work.
Comparing values is difficult because I can't see the relative growth between the boxes from year to year, or size of the budget as a whole. I don't quite see how the animation benefits the user, so you may want to scrap it for some sort of differential comparison. I also don't like the delay when I change from year to year. That could be optimized or reduced through the reduction of the animation time.

Yeah, I know it's kind of snarky of me to correct your entire comment here, but I think our community (yeah I know I haven't had my account here long) is overly focused on criticizing. While all the content of your comment was awesome, it could have been stated in a more polite manner.
I'm not sure how to fix the attitude that crops up in developer communities, all I can think to do is point it out when people may be coming off in way they don't mean to. Which is probably the root cause for this https://news.ycombinator.com/item?id=6353957
