Study Notes
Graph Basics
- Nodes in a graph are also known as vertices.
- The set of edges in a graph is typically represented as E (Edges) or Ε.
- A social network is an example of the type of network that can be represented using graphs in data structures.
- An edge in a graph is a connection between two vertices, representing a relationship between them.
- An empty set of edges in a graph indicates that there are no relationships between the vertices.
