star_graph

star_graph(n, create_using=None)

Return the star graph

The star graph consists of one center node connected to n outer nodes.

Parameters

nint or iterable

If an integer, node labels are 0 to n with center 0. If an iterable of nodes, the center is the first.

create_usingNetworkX graph constructor, optional (default=nx.Graph)

Graph type to create. If graph instance, then cleared before populated.

Notes

The graph has n+1 nodes for integer n. So star_graph(3) is the same as star_graph(range(4)).
