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. WebAn adjacency list is a hybrid between an adjacency matrix and an edge list that serves as the most common representation of a graph, due to its ability to easily reference a vertex 's neighbors through a linked list. Through the use of adjacency list, it is easy to look up a node's neighbors in constant or O (1) time.
