[FR] Support Mind Map

[Tumb1eweed]

1~3 main use cases of the proposed feature Ex: Notion doesn't have mind map, it use embedded whimsical or gitmind instead. I want AppFlowy to have its own embedded mind map.

what types of users can benefit from using your proposed feature Ex: especially students, because students and teachers use mind map very often.

Great idea!

Maybe we can use eg. https://pub.dev/packages/graphite

I believe similar to the free-hand drawing feature, that it would be best to have a read-only view in the Document page itself, that can then be opened up in an expanded read or edit mode.

it seems like this issue and #197 both refer to the same request. I would suggest to close #197 and keep this one open as it got more interaction :)

I would love to see this feature in AppFlowy !
