C# 使用GraphSharp从图形和鼠标事件更改节点布局

我正在使用GraphSharp构建一些图形。 我正在使用的代码用其名称构造顶点（请参见下图：）

我想做的是：“隐藏”节点的名称，并将顶点布局更改为圆形，而不是名称（类似以下内容：）

此外，我想在鼠标指针位于节点上方时显示节点的名称（来自第一个img的名称）

可能吗

这是我的密码：

xaml：

cs

public partial class MainWindow : Window
{
    public IBidirectionalGraph<object, IEdge<object>> _graphToVisualize;
    //public IUndirectedGraph<object,IEdge<object>> _graphToVisualize;

    public IBidirectionalGraph<object, IEdge<object>> GraphToVisualize
    //public IUndirectedGraph<object, IEdge<object>> GraphToVisualize
    {
        get { return _graphToVisualize; }
    }

    public MainWindow(int[,] matrix, string[] names)
    {
        CreateGraphToVisualize(matrix, names);

        InitializeComponent();            
    }

    public void CreateGraphToVisualize(int[,] matrix, string[] names)
    {
        var g = new BidirectionalGraph<object, IEdge<object>>();
        //var g=new UndirectedGraph<object, IEdge<object>>();

        //add the vertices do the graph
        string[] vertices = new string[matrix.GetLength(0)];

        for (int i = 0; i < matrix.GetLength(0); i++)
        {
            vertices[i] = names[i];
            g.AddVertex(vertices[i]);
        }

                if(matrix[i,j]==1) g.AddEdge(new Edge<object>(vertices[i], vertices[j]));

    }
}
