有没有办法在某些情况下水平显示框，而在其他情况下垂直显示框？（请参见相关问题）。
这是我得到的代码和输出：
代码：

输出:
显然，这太长了。我想要的是将每个突触移动到自己的一行中（我认为在Graphviz术语中称为“等级”）。显然，没有办法做到这一点，但有一个技巧。因此，我使用与上面相同的代码，并引入不可见边，如下所示：

}
}
}
现在输出看起来更有吸引力了。
输出:
但是现在突触盒之间存在巨大的间隙。设置nodesep=0.1或len=0.1没有效果。有人能告诉我如何解决这个问题，或者如何重新设计它吗？
注意：如果有人好奇为什么我从1到2到n，那是因为我打算在那里放一个椭圆形，但我不知道如何做...等我到那时再考虑。
