我实现了一些图形算法，并希望展示它们。我用过Jung 2.0

我想为节点添加名称。我设法在边缘写东西，但是我也想显示一个节点的名字。

这是我的代码：

Graph<Integer, String> graph3 = new DelegateForest<Integer, String>();

        graph3.addVertex(1);
        graph3.addVertex(2);
        graph3.addVertex(3);

        graph3.addEdge("RAD-A", 1, 2);
        graph3.addEdge("RAD-B", 1, 3);

        Layout<Integer, String> layout3 = new TreeLayout<Integer, String>((Forest<Integer, String>) graph3);
        VisualizationViewer<Integer, String> vv3 = new  VisualizationViewer<Integer,String>(layout3);

        Transformer<String, String> transformer3 = new Transformer<String, String>() {

            @Override 
            public String transform(String arg0){
                return arg0;
            }
        };

        vv3.getRenderContext().setEdgeLabelTransformer(transformer3);

        transformer3 = new Transformer<String, String>() {
            @Override 
            public String transform(String arg0){
                return arg0;
            }
        };

        final DefaultModalGraphMouse<String,Number> graphMouse3 = new DefaultModalGraphMouse<String,Number>();
        vv3.setGraphMouse(graphMouse3);
        graphMouse3.setMode(ModalGraphMouse.Mode.PICKING);


        JFrame frame3 = new JFrame("Pas 3");
        frame3.getContentPane().add(vv3);
        frame3.pack();
        frame3.setSize(350, 300);
        frame3.setVisible(true);
