Hello, I am a begginer in JUNG and have being tried to make a graph that will
automatically sort according to a number that characterizes the edge (that will
be between 0 and 1). I have done the basic part,creating the graph.How can it
be sorted according to these labels? (two vertexes having 1 as an edge label
must be far away while two others having e.g 0.04 must be very close). I also
need to create a filter that will first remove the edges with large number.
Plz help me if u can. What I have done so far is:

		Graph g = new UndirectedSparseGraph();
		Vertex v1 = (Vertex) g.addVertex(new UndirectedSparseVertex());
	    Vertex v2 = (Vertex) g.addVertex(new UndirectedSparseVertex());
	    Vertex v3 = (Vertex) g.addVertex(new UndirectedSparseVertex());
	    Vertex v4 = (Vertex) g.addVertex(new UndirectedSparseVertex());
	    Vertex v5 = (Vertex) g.addVertex(new UndirectedSparseVertex());
	    UndirectedEdge e1 = new UndirectedSparseEdge(v1, v2);
	    UndirectedEdge e2 = new UndirectedSparseEdge(v1, v3);
	    UndirectedEdge e3 = new UndirectedSparseEdge(v3, v4);
	    UndirectedEdge e4 = new UndirectedSparseEdge(v3, v2);
	    UndirectedEdge e5 = new UndirectedSparseEdge(v5, v3);
	    UndirectedEdge e6 = new UndirectedSparseEdge(v1, v5);
        g.addEdge(e1);
        g.addEdge(e2);
        g.addEdge(e3);
        g.addEdge(e4);
        g.addEdge(e5);
        g.addEdge(e6);
        v1.addUserDatum("label","File1",UserData.SHARED);
        v2.addUserDatum("label","File2",UserData.SHARED); 
        v3.addUserDatum("label","File3",UserData.SHARED); 
        v4.addUserDatum("label","File4",UserData.SHARED); 
        v5.addUserDatum("label","File5",UserData.SHARED); 
        e1.addUserDatum("label","0.77",UserData.SHARED); 
        e2.addUserDatum("label","0.45",UserData.SHARED); 
        e3.addUserDatum("label","0.88",UserData.SHARED); 
        e4.addUserDatum("label","0.99",UserData.SHARED); 
        e5.addUserDatum("label","0.45",UserData.SHARED); 
        e6.addUserDatum("label","0.48",UserData.SHARED); 
 
        PluggableRenderer pr = new PluggableRenderer();
        
        EdgeStringer es = new EdgeStringer() { 
         public String getLabel(Edge e) { 
         return (String)e.getUserDatum("label"); 
         } 
         };

		VertexStringer vs = new VertexStringer() { 
         public String getLabel(Vertex v) { 
         return (String)v.getUserDatum("label"); 
         } 
         }; 
        pr.setVertexStringer(vs);
        pr.setEdgeStringer(es); 
        
        

	    Layout layout = new KKLayout(g);
        vv = new VisualizationViewer(layout, pr);
        vv.setGraphLayout(layout);
