constructs the graph whose vertices correspond to and edges between pairs of vertices and in for which the binary relation defined by the Boolean function is True.
can be set to Directed or Undirected and this tells whether to construct a directed or an undirected graph. The default setting is Directed.
VertexLabel can be set to True or False, with False being the default setting. Using VertexLabel->True assigns labels derived from v to the vertices of the graph.
