A line connecting two elements tells the brain they belong together more powerfully than almost any other visual cue. The Law of Uniform Connectedness, described by Stephen Palmer and Irvin Rock in 1994, holds that elements visually connected by lines, shared fills, or enclosures are perceived as more related than elements sharing any other Gestalt property, including proximity and similarity. A connecting line overrides spatial separation. Two distant elements joined by a line are perceived as a unit; two adjacent elements without a connection are perceived as separate.
