Paraphrasing the website: Gato - the Graph Animation Toolbox - is software [toolkit] which visualizes algorithms on graphs. - Graphs are mathematical objects consisting of vertices, and edges connecting pairs of vertices. - Algorithms might find a shortest path - the fastest route - or a minimal spanning tree or solve one of other interesting problems on graphs: maximal-flow, weighted and non-weighted matching and min-cost flow. - Visualisation means linking cause - the statements of an algorithm - immediately to an effect - changes to the graph the algorithm has as its input - by terms of blinking, changing colors and other visual effects.
