BFS vs DFS Graph Traversal

Description

Shows an 8-node undirected graph and demonstrates two traversal strategies: BFS spreads level by level using a queue, while DFS dives deep using a stack. Visited nodes are colored and the visit order is displayed for each strategy.

Phases

# Phase Name Duration Description
1 Title Card 3s Title fades in
2 Graph Intro 4s 8 nodes and edges appear
3 BFS Label 2s "Breadth-First Search" label; queue visual
4 BFS Traversal 12s Node 0 start; queue shown; level-by-level coloring
5 Reset 2s Graph resets to unvisited
6 DFS Label 2s "Depth-First Search" label; stack visual
7 DFS Traversal 12s Node 0 start; stack shown; deep-first coloring
8 Comparison 5s Side-by-side visit orders for BFS and DFS
9 Outro 2s Fade out
