Cluster extruded nodes in Graphviz

By Load Balance

I want to draw several related subgraphs in GraphViz. When I draw simple nodes, it looks very beautiful:

enter image description here

Resources:

digraph {
 rankdir=LR;

 A1 -> A21;
 A1 -> A22;
 A1 -> A23;
 A1 -> A24;

 B1 -> B21;
 B1 -> B22;
 B1 -> B23;
 B1 -> B24;

 A21 -> A31;
 A22 -> A31;
 A23 -> A31;

 A23 -> A32;

 B21 -> B31 ;

 B21 -> B32;
 B22 -> B32;

 B21 -> B33;
 B23 -> B33;
}

Since the nodes of the same level in several subgraphs are related, I want to group them and give it a label.
I tried to do it with clustering, but it “squeezed” the nodes:< /p>

enter image description here

Resources: 

digraph {
 rankdir=LR;

 subgraph cluster_level1 {
 label = "Level 1";
 style= filled;
 color=lightgrey;

 A1;
 B1;
 }

 subgraph cluster_level2 {
 label = "Level 2";
 style=filled;
 color=lightgrey;

 A21;
 A22;
 A23;
 A24;

 B21;
 B22; 
 B23;
 B24;
 }

 subgraph cluster_level3 {
 label = "Level 3";
 style=filled;
 color=lightgrey;

 A31;
 A32;

 B31;
 B32;
 B33;
 }

 A1 -> A21;
 A1 -> A22;
 A1 -> A23;
 A1 -> A24;

 B1 -> B21 ;
 B1 -> B22;
 B1 -> B23;
 B1 -> B24;

 A21 -> A31;
 A22 -> A31; 
 A23 -> A31;

 A23 -> A32;

 B21 -> B31;

 B21 -> B32;
 B22 -> B32;

 B21 -> B33;
 B23 -> B33;
}

There are only two subgraphs, which is terrible, But still not very bad. But if I add more subgraphs, it will become more ugly and ugly.

Is there a way to group nodes with some shadows and labels while keeping them using GraphViz Original node layout?

This may not be a good answer, because it means a lot of trial and error, but at least You get the (I guess) invisible nodes you want: 

digraph {
 rankdir=LR;

 subgraph cluster_level1 {
 label = "Level 1";
 style=filled;
 color=lightgrey;
 A01[ style = invis ];
 A1;
 A02[ style = invis ];
 A03[ style = invis ];
 A06[ style = invis ];
 A05[ style = invis ];
 B1;
 A04[ style = invis ];
 }

 subgraph cluster_level2 {
 label = "Level 2";
 style=filled;
 color=lightgrey ;

 A21;
 A22;
 A23;
 A24;

 B21;
 B22;
 B23 ;
 B24;
 }

 subgraph cluster_level3 {
 label = "Level 3";
 style=filled;
 color=lightgrey; 

 A07[ style = invis ];
 A31;
 A32;
 A08[ style = invis ]; 

 B31;< br /> B32;
 B33;
 A01[ style = invis ];
 A09[ style = invis ];
 }

 A1 -> A21 ;
 A1 -> A22;
 A1 -> A23;
 A1 -> A24;

 B1 -> B21;
 B1 -> B22; 
 B1 -> B23;
 B1 -> B24;

 A21 -> A31;
 A22 -> A31;
 A23 -> A31;< br />
 A23 -> A32;

 B21 -> B31;

 B21 -> B32;
 B22 -> B32;

 B21 -> B33;
 B23 -> B33;
}
