Module graph_utils 

Functions

clone_subgraph

Creates a new minimal Graph containing only the specified nodes and the edges connecting them.

get_upstream_nodes

Returns all nodes that are upstream (ancestors) of the target node, including the target itself. Only considers Normal edges (not Feedback) to avoid capturing entire feedback loops if not necessary.

topological_sort

Sorts the graph nodes topologically. If cycles are detected, they are returned as well.
