我想使用Graphviz创建一个流程图(类似于Visio).这是一个示例图.

digraph start_up {
node [style = rounded]; 
node [shape = rect] start end;
node [style = ""];
node [shape = diamond] "USB\nCommand\nArrived";
start -> "Initialize\nCode";
"Initialize\nCode" -> "USB\nCommand\nArrived";
"USB\nCommand\nArrived" -> "USB\nCommand\nArrived" [label="No" tailport=w headport=n];
"USB\nCommand\nArrived" -> "Has USB 3.0\nInterface Been\nSelected" [label = "Yes"];
 "Has USB 3.0\nInterface Been\nSelected" -> end
}

问题是当我在Graphviz中渲染这个由"USB\nCommand\nArrived" -> "USB\nCommand\nArrived" [label="No" tailport=w headport=n]; 看起来非常难看的行创建时.我不介意曲线,但这条线看起来变形了.您可以在此处查看Graphviz创建的内容

有没有办法让这个看起来更好？
