Introduction to Graphs Data Structure

Graphs are a non-linear data structure that consists of a finite set of vertices (nodes) and a set of edges connecting them.
In this video, I have introduced the basics, applications, properties and the terminology related to graphs.

06:30 Graph properties
07:05 Connected / Disconnected graph
08:33 Directed / Undirected graph
09:58 Weighted graph
12:21 Cyclic / Acyclic graph
14:05 Dense / Sparse graph
15:03 Simple / Complete graph
16:38 Strongly connected graph
