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.

Jul 23, 2025 · Graph is a non-linear data structure like tree data structure. The limitation of tree is, it can only represent hierarchical data. For situations where nodes or vertices are randomly connected with …

Graphs are mathematical concepts that have found many uses in computer science. Graphs come in many different flavors, many of which have found uses in computer programs.

This page introduces you to the different types of graph. You can also discover more about how graphs are implemented and how graphs are traversed, as well as the use of trees.

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 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 …

Oct 13, 2025 · Graphs are node-based structures (or "linked structures"), and they should look somewhat familiar already from our explorations of linked lists and trees earlier this quarter. Some …

Aug 21, 2024 · In computer science, graph theory underpins many algorithms and data structures used to represent networks such as the internet, social networks, and communication systems.

Oct 2, 2024 · Learn about Graphs for your A Level Computer Science exam. This revision note includes nodes, edges, traversals in graph theory and applications in computing.

Nov 24, 2025 · A graph is a non-linear data structure made up of vertices (nodes) and edges (connections) that represent relationships between objects. Unlike arrays or linked lists, graphs do …
