Introduction to Graphs
What is a Graph?
A graph is a non-linear data structure consisting of vertices (or nodes) and edges that connect these vertices. It's used to represent relationships between different objects.
Key Components:
- Vertex/Node: A fundamental unit of a graph that holds data
- Edge: A connection between two vertices
- Adjacency: Two vertices are adjacent if there's an edge connecting them
