You could spend hours playing with the recently upgraded D.C. Geographic Information System. Having done so myself, I’ll save you the trouble. Here, in no particular order, are a few dozen maps of the geography of all sorts of city features you never even considered, plus a few you may actually have been curious about. Some things (libraries, tennis courts, speed cameras) are spread evenly throughout the city; others are concentrated in wealthier (sidewalk cafes, grocery stores), poorer (public housing, closed public schools), or more densely populated (post offices, liquor licenses) neighborhoods.
