Directed Acyclic Graph (DAG)

A Directed Acyclic Graph (DAG) is a visual representation of data or processes where items are connected by arrows showing relationships, with no loops or cycles—meaning you can’t start at one point and follow arrows back to it. Think of it like a family tree or a project workflow: tasks or elements are arranged in a way that illustrates dependencies or order, but no path loops back. DAGs are used in many fields, including computer science and data management, to organize and process information efficiently without circular references.
