Graphviz: how to have sub-graph nodes lined-up in a straight line?

The simplest solution is to set the weight of the branching and merging edges to 0.

You can use the attribute setting rank=same.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
