Returns the cycle graph \(C_n\) of cyclically connected nodes.
\(C_n\) is a path with its two end-nodes connected.
n (int or iterable container of nodes) – If n is an integer, nodes are from
range(n). If n is a container of nodes, those nodes appear in the graph.
create_using (NetworkX graph constructor, optional (default=nx.Graph)) – Graph type to create. If graph instance, then cleared before populated.
If create_using is directed, the direction is in increasing order.
