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.
