Comparative size of Government

Chris Briem put together this cool visualization (50 MB PDF) showing the Size of Governments in the US, where the number of employees is proportional to the font width. Explained here. I only wish it were searchable.
This might be useful to look at as a Cartogram. But I don’t know if cartograms can handle hierarchical and overlapping jurisdictions (Minneapolis School District is in Minneapolis is in Hennepin is in Minnesota).
