For many people, maps are support for the story. The very essence of a map is that it's made for a client for a specific reason. The client and the reason determine what goes on the map, how it looks, and so on. If you are your own client (isn't there a lawyerly saying along those lines?), then you alone determine why you're doing the map and what goes on it. It's possible to have software generate many, many pictures per hour that look like maps. But are they truly maps?
