Graphviz (点)中的非确定性结果

Question

如何强制graphviz始终生成相同的布局？

给出一个图表：

digraph {
    subgraph clusterA {
        subgraph clusterB {
            "B.001"
            "B.002"
            "B.003"
            "B.004"
        }
        subgraph clusterC {
            "C.001"
            "C.002"
            "C.003"
        }
    }
    subgraph clusterD {
        subgraph clusterE {
            "E.001"
        }
        subgraph clusterF {
            "F.001"
            "F.002"
            "F.003"
        }
        subgraph clusterG {
            "G.001"
            "G.002"
        }
    }
    subgraph clusterH {
        "H.001"
    }
    "G.002" -> "F.003"
    "F.001" -> "C.003"
    "G.002" -> "F.002"
    "G.002" -> "D.001"
}

当我将其传递给dot时，它有时会生成如下布局的结果：

有时就像这样：

显然，第一个看起来要好得多，我希望graphviz坚持使用这个。

我试图通过fdp和unflatten传递我的图形，但是它没有改变任何东西。

我尝试了很多不同的在线和cli渲染解决方案。除了你的第二个输出，我看不到其他的输出。但如果您更喜欢第一个，只需交换ClusterB和ClusterC的顺序即可。

digraph {
rankdir=TB
subgraph clusterA {

    subgraph clusterC {
        "C.001"
        "C.002"
        "C.003"
    }

    subgraph clusterB {
        "B.001"
        "B.002"
        "B.003"
        "B.004"
    }

}

subgraph clusterD {
    subgraph clusterE {
        "E.001"
    }
    subgraph clusterF {
        "F.001"
        "F.002"
        "F.003"
    }
    subgraph clusterG {
        "G.001"
        "G.002"
    }
}

subgraph clusterH {
    "H.001"
}


"G.002" -> "F.003"
"F.001" -> "C.003"
"G.002" -> "F.002"
"G.002" -> "D.001"

}
