Introduction to Graphs
Understand graph fundamentals by exploring vertices, edges, paths, cycles, and adjacency. Learn how graphs represent complex connections used in social networks, navigation, and communication systems. Gain foundational knowledge to implement graphs and describe their key components effectively.
A graph is a non-linear data structure made up of two main components:
Vertices (nodes)
Edges
A vertex represents an object, person, place, or thing, while an edge represents a connection or relationship between two vertices.
Unlike linear data structures such as arrays or linked lists, graphs are designed to represent complex relationships where elements can be connected in many different ways.
Why graphs matter
Graphs are extremely useful because many ...
