Graph. A graph is made out of nodes and directed edges which defines a connection from one node to another node. A node (or vertex) is a discrete position in a graph. Edges can be directed an undirected.Edges have an associated distance (also called costs or weight). The distance between two nodes a and b is labeled as [a,b]. graph is made out of nodes and directed edges which defines a connection from one node to another node. A node (or vertex) is a discrete position in a graph. Edges can be directed an undirected. Edges have an associated distance (also called costs or weight).
