A little history for folks seeing this for the first time: Ishkur has been publishing and updating this for over 25 years.

Truly one of the best artifacts of "the old internet". This gives me nostalgia. So many late nights as a teenager learning about the music I loved that seemed so inaccessible where I grew up. Thank you, Ishkur.

It's also by now subjectively very "historical." It's possible that if you continued the chart until 2025, the task of documenting all of the sub-genres would be infeasible. Electronic music has exploded in variety since 2010.

A random walk through something like this can be more helpful these days: https://www.music-map.com/ (found on HN last year)
