What it does
VisuAlgo uses animation to explain data structures and algorithms and includes training and testing areas.
Watch a small example change step by step, then describe the operation without relying on the animation. That connection is useful when implementing a structure yourself. The training area offers another way to check whether the visual explanation has become an executable mental model. You can supply your own input rather than only watching a preset example. For graph topics, that includes drawing a graph, which helps test how a changed case affects the algorithm.
