在GraphViz中与单个高节点并行排列多个短节点

我想生成这样的东西 - 节点的对齐是重要的,而不是边缘的角度:

+--------------+
|              |
+--------------+
   |        |
   V        V
+-----+  +-----+  <--- alignment at top
|     |  |     |
|     |->|     |
|     |  |     |
+-----+  |     |
   |     |     |
   V     |     |
+-----+  |     |
|     |  |     |
|     |->|     |
|     |  |     |
+-----+  +-----+  <--- alignment at bottom
   |        |
   V        V
+--------------+
|              |
+--------------+

我能想到的最好的方法是将两个左边的节点粘贴到一个带有白色(=&gt;不可见)边框的簇子图中,并将其中一个边的权重设置为0.但它是仍然不太正确:

digraph G {

    // scale things down for example
    size="5,5" 
    rankdir=TD
    ranksep=1
    nodesep=1

    node [shape=box]

    node [width=5 height=2]
    top

    subgraph cluster_left
    {
        color=white
        node [width=2 height=2]
        left1
        left2
    }

    node [width=2 height=5]
    right

    node [width=5 height=2]
    bottom

    top->left1
    top->right

    left1->left2
    left1->right
    left2->right [weight=0]

    left2->bottom
    right->bottom
}

这就像这样 - 对齐不好:

关于如何获得我想要的任何想法?

我是用neato和这个剧本做的:

digraph G {
  layout="neato"
  // scale things down for example
  size="5,5" 
  rankdir=TD
  ranksep=1
  nodesep=1

  node [shape=box]

  top[pos="5,10!", width=5, height=2]

  left1[pos="3.5,7!", width=2, height=2]
  left2[pos="3.5,4!", width=2, height=2]

  right[pos="6.5,5.5!", width=2, height=5]

  bottom[pos="5,1!", width=5, height=2]

  top->left1
  top->right

  left1->left2
  left1->right
  left2->right

  left2->bottom
  right->bottom
}

结果如下:
