The opts argument can contain one or more of the options shown below.

directed=true or false

This option specifies whether the resulting graph should be directed. The default is false.

edgelabels=e

Specifies labels for the edges for use with DrawGraph. The value is a set of equations in which the left-hand side of each equation is an edge and the right-hand side is a string specifying the desired label.

Each edge must be expressed as a list of vertices if the graph is directed and as a set of vertices if it is undirected.

The default is the empty set.

layout=true or false

This option specifies whether a default coordinate assignment for the vertices of the graph should be made. The default is true.

CycleGraph(n) outputs a graph which is a cycle on n vertices labeled 1, 2, ..., n.

PathGraph(n) outputs a graph which is a path on n vertices labeled 1, 2, ..., n.

In both cases you can input the labels for the vertices as a list of integers, strings, or symbols.
