And it's unlikely that any software would produce the map [above], drawn for a Slate reader by a friend: It's a guide to the neighborhoods of Paris, put in terms a young New Yorker can understand. Although the map is simplistic and juvenile, the effort to match Parisian arrondissements with demographically corresponding areas in Brooklyn is a conceptually interesting way to present information about an unfamiliar town.
