In mathematics, and more specifically in graph theory, a graph is a representation of a set of objects where some pairs of objects are connected by links. Graphs are incredibly important part of Modern day life. We come across them almost daily. For example we can reach our office via separate ways possible but which one to take(Considering distance, traffic). Whole of social media like Facebook, twitter, linkedin is nothing but a huge graph with people acting as node and their relationship(friendship) acting like links or edges. Computer networks, electricity distribution network, city pipeline network, road network, airline network, Internet are nothing but a form of a Graph. There are several types of Graphs such as Directed, Undirected, Tree, Weighted, Cyclic, Acyclic etc to name a few of them. And we find examples of almost all of them in real life.
