graphviz 箭头、节点、表格 - 我正在寻找避免双箭头的解决方案？

Question

我生成了 graphviz 的代码。该网络规划始终包含 2 个用于往返方向的箭头。不幸的是，示例中显示了 2 个单独的箭头 - 但我不希望这样......

()

有人知道如何避免红色双箭头吗？是否还需要考虑其他选择？

digraph {

node [shape=box, style=filled, fillcolor=white, color=grey, margin=0];

graph [bgcolor=floralwhite];

edge[arrowhead="normal", color="darkblue", arrowsize=1];

concentrate=true;

删除其中一条边并添加 dir=both 作为另一条边的属性。
