RECIPROCITY (not neighboring)

The less space a set of objects takes, the less likely related things are to be neighboring. (colloquially: “The closer things are together, the less neighboring related things will be.”)
Note: This lack of space, or closeness, can consist of restriction to low dimension. For example, a finite graph that is not planar can easily be drawn non-intersectionally in 3-space.
