Graph Traversal is a method used to visit all the nodes or vertices in a graph. It helps in exploring the structure of the graph, which can represent various real-world scenarios like social networks, transportation systems, or web pages. The two primary techniques for graph traversal are Depth-First Search (DFS) and Breadth-First Search (BFS). In DFS, the traversal goes as deep as possible along a branch before backtracking, while in BFS, it explores all neighbors at the present depth prior to moving on to nodes at the next depth level. Both methods are essential for tasks like searching, pathfinding, and analyzing graph properties.
