   :align: center
   :caption: 这是一个由graphviz绘制的图
   :name: graphviz1

   digraph UML {
      node[fontname = "LXGWWenKai-Regular", fontsize = 10, shape = record];
      edge[fontname = "LXGWWenKai-Regular", fontsize = 10, arrowhead = "empty"];

      Car[label = "{Car | v: float\nt : float | run() : float}"]

      subgraph clusterSome{
          bgcolor = "yellow";
          Bus[label = "{Bus | | carryPeople() : void}"];
          Bike[label = "{bike | | ride() : void}"];
      }
      Bus -> Car
      Bike -> Car
   }
