Commutative Square Diagram in Category Theory - Visual Explanation #2217260 (License: Personal Use)

This diagram depicts a commutative square in category theory, where objects A, B, C, and D are connected by morphisms (arrows). The square commutes if the composition A→B→D equals A→C→D, meaning both paths from A to D are equivalent. Such diagrams formalize relationships like pullbacks, pushouts, and natural transformations.
