Graphs and subgraphs layout
Using graphviz I want to generate the following graph (manually written in tikz for now):
I currently succeeded in writing a dot file giving me the following result (there is a single node using html for the Pile table on the top, and one node also using html for every grey box):
But unfortunately I was not able to keep the layout of grey boxes that I like AND to have the grey boxes on the right of the Pile table. I read carefully this related question and tried things with rank, subgraphs and rankdir without success.
Is there any hope to reach my goal with dot ?
EDIT: here is the complete dot file I have currently
digraph structs {
node [shape=plaintext]
subgraph stack {
label = STACK;

Solution
Minor changes
- changed subgraphs to clusters (see https://www.graphviz.org/pdf/dotguide.pdf)
- added invisible edge to drive cluster positioning
digraph structs {
node [shape=plaintext]
subgraph cluster_stack { // changed to cluster
graph [peripheries=0] // no box around this cluster
label = STACK;
stack [label=<
