Wheel Graph using Networkx Python
  • Last Updated : 02 Feb, 2021

A wheel graph is a type of graph in which if we connect each node in an n-1 node cycle graph to nth node kept at the centre we get a wheel graph. The definition would be more clear after seeing the example below.

Wheel Graph with n nodes is represented by Wn .






Properties of Wheel Graph:

  • Total number of edges are 2(N-1)
  • It is a planar graph.
  • The diameter of the wheel graph is 2 if n>4 or 1 if n=4.
  • It is a kind of Hamiltonian Graph.
  • Wheel Graph with n nodes is represented by Wn .
  • It is a cyclic graph.

We will use the networkx module for realizing a Wheel graph. It comes with an inbuilt function networkx.wheel_graph() and can be illustrated using the networkx.draw() method. This module in Python is used for visualizing and analyzing different kinds of graphs.




  • N: Number of nodes in wheel graph.
  • Returns a wheel graph object.

networkx.draw(G, node_size, node_color)

  • Used to realize the graph by passing graph object.
  • G: It refers to the Wheel graph object
  • node_size: It refers to the size of nodes.
  • node_color: It refers to color of the nodes.


  • We will import the required module network
  • We will set the number of nodes or n=5.
  • Then we will create a graph object using networkx.wheel_graph(n).
  • For realizing the graph, we will use networkx.draw(G).
  • This will print the required wheel graph.



# import required module
import networkx
# number of nodes
n = 5
# create object
G = networkx.wheel_graph(n)
# ilustrate graph



As we initialized n=5 the wheel graph with 5 nodes with a cycle graph having 4 nodes and a central node connected to all other nodes is printed using networkx inbuilt draw function.
