WebNov 2, 2024 · Graphs are non-linear data structures made up of two major components: 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. Edges – Edges represent the relationship between the vertices in the graph. WebVertex A vertex is the most basic part of a graph and it is also called a node.Throughout we'll call it note.A vertex may also have additional information and we'll call it as payload.; Edge An edge is another basic part of a graph, and it connects two vertices/ Edges may be one-way or two-way.
