Example uses of a directed acyclic graph in programming include more or less anything that represents connectivity and causality.

For example, suppose you have a computation pipeline that is configurable at runtime. As one example of this, suppose computations A,B,C,D,E,F, and G depend on each other: A depends on C, C depends on E and F, B depends on D and E, and D depends on F. This can be represented as a DAG.
