Align groups with different widths in LayeredDigraphLayout

Hi,

The following graph displays two groups with different widths. And the groups are center-aligned by default.

Is there any configuration that we can apply to left-align the groups like the following? Thanks so much!

Try the custom AlignedLayeredDigraphLayout that is at: Aligned Layered Digraph Layout
As always, the complete source code is in the page itself.

Thank you Walter. The sample page looks exactly what I need. I will study the code.
