The thing is Rock subgenres are a lot broader than Electronic subgenres. The two scenes categorize genres differently, and while Rock based it's genres on a more general sound EDM is a lot more specific and technical with the way it categorizes things. The person is categorizing EDM subgenres with a more Rock like approach.
EDIT: Apparently the site was algorithmically-generated, so depending on what the algorithm is and what it determined by the algorithm is how many grains of salt to take. I looked up Tool and got stuff like "rap rock", so the genres for individual artists is definitely algorithmically-generated. What I find interesting is how the top-left corner is the metal cluster, the top right corner is the classical cluster, and the bottom left corner is "afro-dance" cluster, and how the bottom-right corner is completely empty (except for oratory, which isn't even really music). I guess the most useful way to look at this is by comparing metal to everything else, metal is the most useful spot because of the way the graph is distributed.
