Other Layouts in mindmap?

[Jeff-Tian]

Is mermaid mindmap supporting this kind of layout?

This is super important in my opinion because mindmaps become difficult to use when number of items increases. The items start overlapping.

There's currently no way to change the structure of the mindmap in mermaid as per the documentation.

It would be nice to see the mind map diagram expand, as the issue @sudhirkhanger raised is valid.

Personally I feel like the mermaid mind map is great up till roughly 20 elements, spread evenly.

Above that, and what might be useful for you, I use flowcharts instead. It's not entirely what they're designed for, but they work really well imo.
Here's an example:

flowchart LR
    root([Debian])
    A([Ubuntu])
    AA([Linux Mint])
    AB([Kubuntu])
    B([LMDE])
    C([SolydXK])
    CC([1 deep])
    CCC([2 deep])

    root --- A & B & C
    A --- AA & AB 
    C --- CC --- CCC

Playing with chaining of links is important and can be quite useful.
