如何从Graphviz正确转换为Python

Question

我正在尝试从graphviz转换为python。

我认为“虚拟”节点和“虚拟”边缘存在问题。 当我插入g.attr（compound =“ true”）行时，也会出现错误。

Graphviz：

digraph G {
    compound=true;
    node [shape=box];
    edge [dir=none];

    subgraph cluster_overall{
            subgraph cluster_top{
            dummy_top [shape=point width=0 style=invis]
            apple;
            banana;
            }
            subgraph cluster_basket{
            dummy_basket [shape=point width=0 style=invis]
            basket1;
            basket2;
            label="Baskets";
            }
            subgraph cluster_bottom{
            dummy_bottom [shape=point width=0 style=invis]
            orange;
            kiwi;
            }
    label="Test";
    }
    dummy_top -> dummy_basket [
        style=invis
        weight=100
        lhead="cluster_basket"
        ltail="cluster_top"
    ]
    dummy_basket -> dummy_bottom [
        style=invis
        weight=100
        lhead="cluster_bottom"
        ltail="cluster_basket"
    ]
    apple -> basket1;
    banana -> basket2;
    orange -> basket1;
    kiwi -> basket2;

}

到目前为止我的python尝试：

g = Digraph('test2', format='png')

g.attr(compound="true")
g.attr('node', shape='record')
g.attr('edge', dir='none')

with g.subgraph(name="cluster_overall") as a:
    g.attr(label="test")

# Cluster with bottom top of fruits
with g.subgraph(name='cluster_top') as b:
    g.node("dummy_top", shape="point", width="0")
    g.node("apple")
    g.node("banana")

# Cluster with basket
with g.subgraph(name='cluster_basket') as c:
    g.node("dummy_msc", shape="point", width="0")
    g.node("basket1")
    g.node("basket2")

# Cluster with bottom half of fruits
with g.subgraph(name='cluster_bottom') as d:
    g.node("dummy_bottom", shape="point", width="0")
    g.node("kiwi")
    g.node("orange")

g.edge("dummy_top", "dummy_basket", weight="10", lhead="cluster_msc", ltail="cluster_top")
g.edge("dummy_basket", "dummy_bottom", weight="10", lhead="cluster_bottom", ltail="cluster_basket")

g.edge(apple,basket1)
g.edge(banana,basket2)
g.edge(orange,basket1)
g.edge(kiwi,basket2)

g.view()

请让我知道我没有正确解释自己。谢谢。
