Author here! There seems to be some confusion about this visualization, but we can solve it with just two words: Start Clicking! The thing that makes this visualization different than other visualizations is that you can see the individual components of what makes up the large departments. Just double click on any of the boxes. If you single click on any box, you can see how that box changed over time. So, for example, you can see that in 2012 that 2.89% of the budget went to education, but if you double click, you can see that only 13.73% of that went to elementary and secondary education. You can also single click anywhere and see a graph of how things have changed over time. So you can see that in 2009 there was a huge spike in elementary and secondary education, and you can go to 2009 to further investigate, and find there was a "State Fiscal Stabilization Fund" in 2009 that sent $14 billion to education, and then went away. As many have noted, this doesn't do a good job at comparing different departments to each other over time. This isn't a surprise, since a treemap is the completely wrong format to be able to do that. However, it is a very good format for exploring what agencies, bureaus and line items make up the large departments, which is data I've never seen anywhere else before, and why I built this visualization. |
