I searched the internet for some apps that have related functionality (that one could maybe copy and make an Anki addon from it) and found Marginnote 3. Judging from the mindmap-related features they list on their website (https://www.marginnote.com/features) this seem pretty good. Then there is Roam Research and RemNote, for which there is an addon for generating graphs (https://github.com/nhanvu327/rem-graph).
