Binary Circle Grid Patterns - Visual Representation of Logical States #3681115 (License: Personal Use)

The image presents eight 2×2 grids, each containing four circles that are either solid black (filled) or outlined white (empty), forming all possible combinations of four binary elements. These patterns correspond to the 16 possible 4-bit states, though only 8 distinct arrangements appear here-likely representing symmetric or canonical subsets. The layout is clean and monochromatic, emphasizing logical structure over aesthetic flourish.

Used in educational materials on binary logic, combinatorics, or UI pattern libraries; supports user intent to understand visual encoding of discrete states or to select icon variants for toggles or status indicators.
