The DAG (Directed Acyclic Graph) Theory

A Directed Acyclic Graph (DAG) is a visual way to represent relationships where each connection has a direction, showing how one thing influences another, without looping back to the start. It's like a flowchart that moves forward only, ensuring no cycles or infinite loops. DAGs are useful for modeling processes like task dependencies, data workflows, or causal relationships, helping to understand how different elements are connected and progress logically over time or stages. They enable clear mappings of complex systems with clear directional flow and acyclic structures.
