networkx.generators.classic.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:

• n (int 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_using (Graph, optional (default Graph())) – If provided this graph is cleared of nodes and edges and filled with the new graph. Usually used to set the type of the graph.

Notes

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