Returns Zachary’s Karate Club graph.
Each node in the returned graph has a node attribute ‘club’ that indicates the name of the club to which the member represented by that node belongs, either ‘Mr. Hi’ or ‘Officer’. Each edge has a weight based on the number of contexts in which that edge’s incident node members interacted.
To get the name of the club to which a node belongs:
>>> G = nx.karate_club_graph() >>> G.nodes["club"] 'Mr. Hi' >>> G.nodes["club"] 'Officer'
