Test directed graph for weak connectivity.

A directed graph is weakly connected if and only if the graph is connected when the direction of the edge between nodes is ignored.

Note that if a graph is strongly connected (i.e. the graph is connected even when we account for directionality), it is by definition weakly connected as well.

Parameters:G (NetworkX Graph) – A directed graph.
Returns:connected – True if the graph is weakly connected, False otherwise.
Return type:bool
Raises:NetworkXNotImplemented: – If G is undirected.


For directed graphs only.
