A graph is a data structure that is defined by two components :
A node or a vertex.
An edge E or ordered pair is a connection between two nodes u,v that is identified by unique pair(u,v). The pair (u,v) is ordered because (u,v) is not same as (v,u) in case of directed graph.The edge may have a weight or is set to one in case of unweighted graph.
Consider the given below graph, To know about “Graph representation” click here
Applications: Graph is a data structure which is used extensively in our real-life.

WEBA graph G G consists of a pair (V, E) ( V, E), where V V is the set of vertices and E E the set of edges. We write V(G) V ( G) for the vertices of G G and E(G) E ( G) for the edges of G G when necessary to avoid ambiguity, as when more than one graph is under discussion.
