Graphs

Graphs are a fundamental data structure in computer science that model pairwise relationships between objects, consisting of vertices (nodes) and edges (connections). They are used to represent networks such as social connections, transportation systems, or dependencies in software. Graphs enable efficient algorithms for pathfinding, connectivity analysis, and optimization problems.

Also known as: Graph theory, Network, Directed graph, Undirected graph, Graph data structure

Why learn Graphs?

Developers should learn graphs for solving complex problems involving relationships and networks, such as social media friend recommendations, GPS navigation, or dependency resolution in build systems. They are essential in fields like machine learning (graph neural networks), web development (routing), and operations research (scheduling).
