I somehow missed this but Google had a contest in February to find the best data visualisation to represent tax data in an interesting way. The finalists are posted and the results are very impressive. The winner is Anil Kandangath who looks at where US tax dollars went in 2009. It is very intuitive and very useful. It compares very favourably to the White House’s own ‘tax receipt’ launched this month (although this entry does it the way you want; how many burgers was that worth).
On the other ones, this one will charm a libertarian’s heart (you can calculate what you are doing for the government down to the minute), this one was less ambitious but on the same theme with some virtues in simplicity, this one does something more useful in that it compares actual spending to your ‘preferred’ allocation (it reminded me of this Kansas innovation), this one allows you to walk the data with a Kinect, and this one was one of my favourites (interactively adjusting the time series on various data).
Now why isn’t some Australian data-minded politician thinking about engaging the community to visualise more government data?
