stacked same level nodes

[peterejkemp]

Proposal

Some of the diagrams I make are limited by the width of a page of paper, I need to show the same level of nodes stacked on top of each other so I can represent all nodes without them going off the side of the page

Use Cases

diagrams for print and mobile phones

Screenshots

the current implementation is like so:

when I need:

Syntax

in R qmd:

mermaid("
graph TD
    subgraph L3 Countries
        B[Russia]
        C[United Kingdom]
    end
    subgraph L2 Schools
        direction stacked
        D[School 1]
        E[School 2]
        F[School 3]
        G[School 4]
    end

    B --> D
    B --> E
    C --> F
    C --> G
")

Implementation

This is a proposal which I'd love to see built into mermaid by the wonderful community.
