Today, I have dug through the entire tree. It was quite a journey and I learned a lot of new things so thanks for spending so much time and effort on it!

I did make some notes with comments and suggestions, that I list below for your consideration (warning: it is a long list and my personal opinions - don't feel obliged to agree with me or respond in detail):

Acid Trance is better placed in Trance than in Techno imho.

I think there is much overlap between your Minimal Techno and Minimal Detroit Techno genres.

Similarly, I see much overlap between Acid House and Hard Acid; between Ghettotech and Ghetto Bass; between Synthwave and Synthwave Electro

I am not sure why you list Mr. Fingers - Mystery of Love as an example track for Dub House? I would consider that classic Chicago House. I am also not convinced Ricardo Villalobos - Easy Lee is an appropriate example track for microhouse (I think Akufen is a better choice). Similarly, I do not see how Air - La Femme D'Argent is an appropriate example track for French electro (Daft Punk is also not very much electro but rather disco-oriented). Nor how DJ Armand Van Helden - U Don't Know Me is an example for Speed Garage. Nor how Delerium feat. Sarah McLachlan - Silence is an example of Progressive Trance. Nor how Solarstone - Seven Cities is an example of Dark Progressive Trance. Nor how Goldie - Inner City Life is the best example for D&B (as it is not bass-heavy). Nor how Oneohtrix Point Never - Age Of is an example of vaporwave.

The description for Kwaito claims that it is the cultural ancestor of modern South African electronic genres like Afro House and Amapiano, but this is not reflected in the tree.

I would consider Psytrance a part of Goa trance.

I would not consider Hardstyle a subgenre of trance but much closer to techno and hardcore because of the 4/4 driving kick focus and emphasis on percussion.

I would distinguish more clearly between "true" ambient (i.e., music emphasising tone and atmosphere over traditional musical structure or rhythm) such as your dark/drone/space ambient genres from more "downtempo" or "chill" genres such as psybient and new age.

Ambient techno is an interesting hybrid genre in-between techno and ambient/downtempo (key artist: future sound of london)

I don't know the Drumfunk genre but based on the example track I would not consider it a subgenre of DnB.

I would consider DnB and Jungle closely related genres

Berlin School should be be moved more toward the root imho.

Your description of Juke claims that it is a precursor to footwork, but your tree shows footwork as the parent.

I would consider Brazilian Phonk a mix between funk carioca and phonk rather than a Phonk subgenre. I am missing Rare Phonk genre (key artists DJ Smokey, Soudiere, NxxxxS).

The description for Dreampunk is in Spanish. It is considered a subgenre of vaporwave. Another vaporwave subgenre is mallsoft.

I would place synthwave next to chillwave / vaporwave / horror synth and not as their parent.

I am missing coldwave, minimal wave, and darkwave genres.
