Bipartite graph
GRAPH OF TWO DISJOINT SETS IN WHICH EVERY VERTEX IN ONE SET IS CONNECTED TO AT LEAST ONE IN THE OTHER
Bipartitie graph; Bipartite Graph; Bipartite graphs; Bipartite plot
In the mathematical field of graph theory, a bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint and independent sets U and V, that is every edge connects a vertex in U to one in V. Vertex sets U and V are usually called the parts of the graph.
