takes a set and a function from to and constructs a directed graph with vertex set and edges for each in .
constructs a graph with vertex set and edge set for each . An option called Type that takes on the values Directed and Undirected is allowed. Type->Directed is the default, while Type->Undirected returns the corresponding underlying undirected graph.
takes a nonnegative integer and a function from onto itself and produces the directed graph with vertex set and edge set for each vertex .
