Composant Graphvis 2 pour Primefaces : Dijkstra côté serveur


Dijkstra Example:

On "Generate Graph" click, a graph model is randomly generated on the server side and drawn on the client side.
On "Find path" click, server applies the Dijkstra algorithm looking for the shortest path. if a path is found, server applies red color to all path elements, on the client side the graph is updated and the shortest path is shown.
