Implementing Graph Animation

The video tutorial explains how to implement a graph using nodes and adjacency lists. It covers creating a node class with a constructor, value, and adjacency list. The tutorial also discusses building a graph structure, connecting nodes, and handling node visits to prevent infinite loops. The video concludes with a summary and a preview of the next lecture on DFS and BFS.

What is the difference between tree traversal and graph traversal as discussed in the lecture?

In the context of the lecture, what is the significance of creating a node class?

What are the potential issues with visiting nodes in a graph without marking them as visited?
