Graphviz：如何使用circo布局安排节点

我想画一个圆形拓扑图

以下是我希望看到的：

这是我的gv文件：

digraph g1 {
    layout="circo";
    node [shape = doublecircle]; N4 N6;
    node [shape = circle];
    N0 -> N1 [ label = "{1,0}"];
    N1 -> N2 [ label = "{1,0}"];
    N2 -> N3 [ label = "{1,0}"];
    N3 -> N4 [ label = "{1,0}"];
    N4 -> N5 [ label = "{1,0}"];
    N5 -> N6 [ label = "{1,0}"];
    N6 -> N0 [ label = "{1,0}"];

    N0 -> N4 [ label = "{1,0}"];
    N1 -> N5 [ label = "{1,0}"];
    N2 -> N6 [ label = "{1,0}"];
    N3 -> N0 [ label = "{1,0}"];
    N4 -> N1 [ label = "{1,0}"];
    N5 -> N2 [ label = "{1,0}"];
    N6 -> N3 [ label = "{1,0}"];    
}

这是上图的输出图像：

如何在graphviz中排列节点以使其看起来像？

如果目标是拥有一个尊重节点顺序的图形，那么就没有那么简单了。你可以

或者，您可以首先使用确定节点正确顺序的边布局节点：

digraph g1 {
    node [shape = doublecircle]; N4 N6;
    node [shape = circle];
    edge[label="{1,0}"];
    N0 -> N1 -> N2 -> N3 -> N4 -> N5 -> N6 -> N0;
}

与：

然后将剩余的边添加到

tempgraph.gv

-只需在关闭

}

之前复制粘贴以下内容即可：

N0 -> N4 [ label = "{1,0}"];
N1 -> N5 [ label = "{1,0}"];
N2 -> N6 [ label = "{1,0}"];
N3 -> N0 [ label = "{1,0}"];
N4 -> N1 [ label = "{1,0}"];
N5 -> N2 [ label = "{1,0}"];
N6 -> N3 [ label = "{1,0}"];

并使用

neato

和

-n

选项进行渲染：

neato -n tempgraph.gv -Tpng -O

您可能需要微调标签的位置：

谢谢

circo

命令是我想要的，但我只是尝试

dot

和

neato

现在我明白了为什么我不能得到一个圆形布局了！

neato -n tempgraph.gv -Tpng -O
