A node notes feature request for graph and flowchart

While some types of Mermaid diagrams explicitly support notes, I don’t know why graph and flowchart don’t support, I have a habit to make such graphs, and I currently use drawio to draw it:

An awkward workaroud

The current mermaid is difficult to implement Description1. This is my current solution from here:

graph TB
    A -->|"Description2:A how to B"| B --> C
    A ---|"Description1:Properties of A"|A
    B --> D
    D -.-> F
    F ---|"Description1:Properties of F"|F
    C -->|"Description2:C how to F"| F
    F --> H & G & K
    H --> M
    G & K -.-> M
    linkStyle 2,5 stroke:#fff,stroke-width:0px;

But I have to say this solution to implement Description1 is little awkward, It has some defects:

1. Hard to compute the number of this edge when there are many edges
2. This solution will seriously affect the layout of nodes
3. It is very not convenient to distinguish Description2 with different css styles

Suggestion

I think what I need is a node notes feature, such as note right of A: "Description1 Properties of A"? I strongly suggest to add this feature for graph and flowchart

A workaround I’ve used for this is to use subgraphs with unlinked nodes with no style:

flowchart TB

    subgraph A
        A-DESC("Description1:Properties of A")
    end

    subgraph F
        F-DESC("Description1:Properties of F")
    end

    A -->|"Description2:A how to B"| B --> C
    B --> D
    D -.-> F
    C -->|"Description2:C how to F"| F
    F --> H & G & K
    H --> M
    G & K -.-> M

    classDef desc fill:#0000,stroke:#0000,stroke-width:0px;
    classDef subgraphnode fill:#000,stroke:#81B1DB
    class A-DESC desc;
    class F-DESC desc;
    class A subgraphnode;
    class F subgraphnode;

NB: I switched from graph to flowchart

Your difficulties can be solved by a note feature of node , which meets your needs with beautiful layout @Juddd
