Graphs / Shortest Path Pattern Visualizers
The Graphs / Shortest Path pattern is a recurring algorithmic shape that appears across coding interviews and competitive problems. Use it when the problem geometry matches its trigger conditions — recognizing the pattern collapses what looks like a hard problem into a familiar template. These visualizers trace Graphs / Shortest Path step-by-step on classics such as Bellman Ford Algorithm, Dijkstra's Algorithm, Floyd Warshall Algorithm, so you can internalize the moves before you ever need them under pressure.
Graphs
Bellman Ford Algorithm
Computes the absolute shortest paths sequentially from a source node to all other reachable nodes. Safely handles negative edges and detects negative cycles.
