        """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.

        The dataset is derived from the 'Club After Split From Data' column of Table 3 in [1]_.
        This was in turn derived from the 'Club After Fission' column of Table 1 in the
        same paper. Note that the nodes are 0-indexed in NetworkX, but 1-indexed in the
        paper (the 'Individual Number in Matrix C' column of Table 3 starts at 1). This
        means, for example, that ``G.nodes[9]["club"]`` returns 'Officer', which
        corresponds to row 10 of Table 3 in the paper.

        Examples
        --------
        To get the name of the club to which a node belongs::

            >>> G = nx.karate_club_graph()
            >>> G.nodes[5]["club"]
            'Mr. Hi'
            >>> G.nodes[9]["club"]
            'Officer'
