In computer science, a graph is an abstract data type that is meant to implement the undirected graph and directed graph concepts from the field of graph theory within mathematics.

Jan 26, 2026 · Graph is a non-linear data structure like tree data structure. A Graph is composed of a set of vertices (V) and a set of edges (E). The vertices are connected with each other through edges. …

A graph is a data structure that can be used to represent complex, non-linear relationships. A graph consists of nodes (also called vertices) that are connected by edges (also called arcs).

Most graphs are defined as a slight alteration of the following rules. A graph is made up of two sets called Vertices and Edges. The Verticies are drawn from some underlying type, and the set may be …

Aug 21, 2024 · Explore the essentials of graph theory with this beginner's guide. Learn about vertices, edges, and various graph types to understand complex networks and applications.

Jun 7, 2024 · In this tutorial, we’ll discuss some of the most important data structures in computer science – graphs. We’ll first study the basics of graph theory, in order to familiarize ourselves with its …

May 26, 2023 · In computer science, a graph is an abstract representation of a set of objects, known as vertices or nodes, connected by a set of edges. Graphs offer a flexible way to depict relationships...

Jun 15, 2025 · Explore the role of graphs in computer science, including their applications in algorithms, data structures, and software development, and learn how to leverage their power in your own projects.

Two vertices are adjacent if they are connected by a single edge. The collection of vertices that are adjacent to a vertex v are referred to as v’s neighbors. A path is a sequence of edges that connects …

Each line is an edge, connecting two vertices. We denote an edge connecting vertices u and v by the pair (u, v) . Because the "know each other" relationship goes both ways, this graph is undirected. An …
