Maps give you insight to something. We use maps for directions, but we also use them for storytelling, to explain an entire picture or circumstance, and for instruction.
Maps can infer scale, importance, chronology and a multitude of other things. Today we have a large scale map, so large it contains the entire universe. As an added bonus: it is interactive.
