DAG

A Directed Acyclic Graph (DAG) is a visual structure used to represent relationships between objects or tasks, where arrows show the direction of influence or order. "Directed" means each connection has a specific direction, indicating dependency or sequence, while "acyclic" means there are no loops—once you follow the arrows, you won't circle back to the starting point. DAGs are useful for modeling processes like task workflows, data relationships, or decision sequences because they clearly show how elements depend on each other without ambiguity.
