Data Description Improvements

[JohnCRuf]

I want a few new figures:

• [ ] Maps of spending categories. What areas get the most spending on streets, parks, sidewalks and alleys, policing, and misc?
• [ ] Take 50 wards for each cycle from 2003-2022. This should 5 total: (04-07, 08-11, 12-15, 16-19, 19-22). Look at the distribution of a fraction of the total budget spent on top X incumbent supporting precincts in the general election of the previous election for each of the 50 wards in these five periods. This gives 250 numbers. What does this look like? If it is bi-modal, we have a strong case for bringing in Dixit-Londregan results.

Maps are produced here: data_description_improvements. Need to re-color them.
