Types of Graphs

There two types of graphs:
i. Undirected Graphs
ii. Directed Graphs

Undirected Graph: A graph that entail edges with ordered pair of vertices, however it does not have direction define. Example of such a graph is the 'Family tree of the Greek gods'

Directed Graph: A graph that entail edges with ordered pair of vertices and has direction indicated with an arrow. Example of such a graph is the 'A finite-state machine of a light switch'
