Graphviz 不在子图周围绘制边框

Question

考虑以下 Graphviz 代码：

digraph g1 { 
    compound = true;
    node [shape = box, style=filled, fillcolor=Khaki] a;

    subgraph sg1 {
        node [shape = "", style="", fillcolor=""] b -> c;
        graph [style=solid, penwidth=3];
    }
}

这产生：

为什么我在 subgraph/cluster 周围没有边框？

Answer 1

sg1 必须是一个簇才能绘制边框

即。将其重命名为例如。 cluster_sg1
