weakly_connected_components(G)

Notes

For directed graphs only.

Parameters

G : NetworkX graph

A directed graph

Raises

NetworkXNotImplemented

If G is undirected.

Returns

comp : generator of sets

A generator of sets of nodes, one for each weakly connected component of G.

Generate weakly connected components of G.

See Also

connected_components
strongly_connected_components

Examples

Generate a sorted list of weakly connected components, largest first.

>>> G = nx.path_graph(4, create_using=nx.DiGraph())
... nx.add_path(G, [10, 11, 12])
... [
...  len(c)
...  for c in sorted(nx.weakly_connected_components(G), key=len, reverse=True)
... ] [4, 3]

If you only want the largest component, it's more efficient to use max instead of sort:

>>> largest_cc = max(nx.weakly_connected_components(G), key=len)

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
