Each string in the following tuple is a valid triad name:: ( "003", "012", "102", "021D", "021U", "021C", "111D", "111U", "030T", "030C", "201", "120D", "120U", "120C", "210", "300", ) Each triad name corresponds to one of the possible valid digraph on three nodes. Parameters ---------- triad_name : string The name of a triad, as described above. Returns ------- :class:`~networkx.DiGraph` The digraph on three nodes with the given name. The nodes of the graph are the single-character strings 'a', 'b', and 'c'. Raises ------ ValueError If `triad_name` is not the name of a triad.
