Dijkstra's Shortest Path
Description
Visualizes Dijkstra's algorithm on a weighted directed graph with 6 nodes. The animation shows the priority queue (min-heap), greedy node exploration, distance table updates at each step, and the final shortest path tree highlighted in gold.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Intro | 3s | Title and graph displayed with edge weights |
| 2 | Initialization | 4s | Source node highlighted, distance table initialized (0 for source, ∞ for rest) |
| 3 | Priority Queue | 3s | Priority queue shown with initial entry |
| 4 | Exploration Loop | 24s | Iteratively: dequeue minimum, relax edges, update distances and PQ |
| 5 | Final Path | 6s | Shortest path from source to all nodes highlighted in gold |
| 6 | Outro | 4s | Summary of distances shown |
