If you want to make some budget visualizations of your own, let me link this site we've been working on:

http://openspending.org/help/index.html

It's powering a variety of budget sites, like http://wheredoesmymoneygo.org/, http://bund.offenerhaushalt.de/ and http://cameroon.openspending.org/en/. People can just go an upload their own data quickly - OpenStreetMap for money :)
