But not every abstract representation is a map. Maps have axes, usually at least two; they elucidate relationships between features of the domain; and they are useful for orienting, navigating, or engaging in goal-directed behavior within that domain.
Maps that are inscribed on some kind of surface – paper, clay, rock, or an electronic screen – are useful for sharing, pointing at, and comparing with the domain.
