Line Order Adjustment in Mermaid Diagrams

[aCoo4ie]

Proposal

Mermaid.js should provide a way to visualize or adjust the order of lines in the diagram.

Example

Current Mermaid code:

graph TD
  subgraph test
  1-->2
  7-->1
  3-->7
  6-->7
  2-->3
  4-->5
  3-->4
  end

This results in overlapping lines that are hard to adjust.However, when the number of lines in the diagram is relatively large, there will be overlapping, which affects the view, and it is difficult to adjust the order of the lines.
I suggest adding an option or method to adjust the line rendering order more easily.

Alternative solution using subgraph:

graph TD
  <1>7-->1
  <2>1-->2
  <3>2-->3
  3-->4
  3-->7
  4-->5
  6-->7
 end

Screenshots

For example, with the following Mermaid code, it's hard to easily move the leftmost line to the right, as shown in test1 below:

graph TD
    subgraph test
    1-->2
    7-->1
    3-->7
    6-->7
    2-->3
    4-->5
    3-->4
    end

Eventually, using a subgraph approach is the only workaround that somewhat matches the expectation, as shown in test2 below:

graph TD
    subgraph test
        subgraph left
            7
            1
        end
        subgraph right
            2
            3
            4
            5
            6
        end
        7-->1
        1-->2
        2-->3
        3-->4
        3-->7
        4-->5
        6-->7
    end
