DagreLayout计算后节点排布问题

如下图所示，怎么才能使节点“3”和节点“2”在X方向上对齐，是有相关的配置吗？

Start by reproducing the attached DagreLayout arrangement and inspect the available layout configuration for controlling the X positions of nodes 2 and 3. Compare the resulting node coordinates and determine whether the requested alignment is supported by configuration; done means documenting or confirming the relevant setting and its effect.
