Star Graph using Networkx Python Last Updated : 17 May, 2021 Comments Improve Suggest changes Like Article Like Report In this article, we are going to see Star Graph using Networkx Python. A Star graph is a special type of graph in which n-1 vertices have degree 1 and a single vertex have degree n – 1. This looks like that n – 1 vertex is connected to a single central vertex. A star graph with total n – vertex is termed as Sn. Properties of Star Graph: It has n+1 vertices.It has n edges.It does not have any cycle.The diameter of a star graph Sn is a minimum of (2, n).A Star graph is a tree.It has no unconnected component.The chromatic number of the star graph is a minimum of (2, n + 1). Example of S10 : S10 Example of S6 : S6 Approach: We will import the required networkx moduleAfter that, we will initialize a number of nodes to 6.We will create graph object G using star_graph() function.We will realize the graph using nx.draw() function.We will make the color of nodes green and increasing size by passing extra arguments to nx.draw(). Example 1: Python3 # import required module import networkx as nx # create object G = nx.star_graph(6) # illustrate graph nx.draw(G, node_color = 'green', node_size = 100) Output: Explanation: As we passed 6 as an argument to the star_graph() function hence we got a star graph with 6 edges as output. We changed the color and size of nodes by passing extra arguments node_size and node_color to the nx.draw() function. Example 2: Python3 # import required module import networkx as nx # create object G = nx.star_graph(10) # illustrate graph nx.draw(G, node_color = 'green', node_size = 100) Output: Explanation: As we passed 10 as an argument to the star_graph() function hence we got a star graph with 10 edges as output. We changed the color and size of nodes by passing extra arguments node_size and node_color to the nx.draw() function.
