Graphs are non-linear data structures made up of two major components: 1. Vertices– Vertices are entities in a graph. Every vertex has a value associated with it. For example, if we represent a list of cities using a graph, the vertices would represent the cities. 2. Edges– Edges represent the relationship between the … See more Graphs are used everywhere, from schooling to business. Especially in the fields of computer science, physics, and chemistry.
