By using object oriented method design graph vertices into class, and in this foundation to increase visual member, realize from the source point to the other vertex of the shortest path algorithm of dynamic visualization. Around the two sync window animation, the left window with thick lines drawn through the vertices and edges, " revealed the source point to the other vertex of the shortest path " list box display shortest path sequence and path length, the right window demonstration algorithm dynamic implementation process, and in the " S " text box to display the current most find shortest path vertices. The system has friendly interface, visual image.
