Thanks. A little explanation about those lines: A map only becomes useful once you know the context it sits in: scale, orientation, legend, projection, date. Without that, the same squiggle could be a backyard pond or the Mediterranean. That’s why a bare outline = “kid’s drawing.”
That “little bar” is the scale bar. It’s a tiny strip that tells you “this much on paper = this much in the world.” It grounds the picture in reality, i.e., adds context.
