The advantage of Map View is that it can represent relationships other than subordination and linear order. Notes can inhabit any position in two-dimensional space. They can differ in size, shape, shadow position, shadow color, shadow blur, border type, border dash, border color, opacity, font features (family, color, alignment), subtitle, and the color and size of the note’s internal $Text. Each one of these adds a new dimension of variation and, so, information.
