Mapmakers use all sorts of colors, symbols, and fonts to bring their maps to life. It's like a big puzzle, where every piece has to fit together just so.
And have you ever heard of cartographic bias? It's when mapmakers inadvertently (or deliberately!) distort the size or shape of certain features to make a point or promote an agenda.
For example, the Mercator projection makes Europe and North America look way bigger than they really are, while Africa and Asia get shrunk down. It's like a map-based optical illusion!
