What is Graph?
A graph data structure is a collection of nodes (also called vertices) and edges that connect them. Nodes can represent entities, such as people, places, or things, while edges represent relationships between those entities.
Graphs are used to model a wide variety of real-world systems, such as social networks, transportation networks, and computer networks.
Difference Between Graph and Tree
Graphs and trees are two fundamental data structures used in computer science to represent relationships between objects. While they share some similarities, they also have distinct differences that make them suitable for different applications.
