Directed Acyclic Graphs

A Directed Acyclic Graph (DAG) is a type of diagram made up of nodes (points) connected by arrows (edges) that follow a specific direction. "Directed" means the arrows indicate a flow or sequence, and "acyclic" means the connections don't form loops—once you follow the arrows, you can't return to the starting point. DAGs are used to represent processes where certain tasks depend on others, such as task scheduling, data processing, or version histories in software. They help visualize relationships clearly while ensuring there's no circular dependency, making complex workflows easier to understand and manage.
