这个范例演示了连通矩阵的概念，涉及矩阵和图论的核心数学概念。通过使用GeoGebra命令如Circle, Intersect, Rotate等，构建了一个连通矩阵的可视化模型。该范例适合高中数学教学，特别是矩阵和图论相关课程。

AI 绘图提示语参考

绘制一个正十二面体，其顶点均匀分布在以原点为圆心的单位圆上，从圆与水平轴正方向的交点开始，每隔60度旋转生成一个顶点，共得到20个顶点。在十二面体旁边，用表格形式展示一个20行20列的连通性矩阵，行和列分别用A到T的字母标记，矩阵中的数值表示对应顶点之间是否存在棱边连接。同时，在十二面体的棱边中点处标记一个点，以突出棱边的结构。整体构图应清晰展示十二面体的三维几何形状与矩阵的对应关系。
