For me (Firefox on Windows, not in reader mode) the graphics stop showing at the "585 builds" paragraph.
Besides, if something doesn't work in reader mode, it's also likely to not work with screen readers. People who use those don't have much of a choice in what they can enable or not.
I'm not sure how accessible it'd be possible to make those interactive graphs any ways. The description would need to be dynamic since you can change the weights and you could only really decide to highlight a few beyond the maximum. I guess render it out as a table for the screen reader and say GL:HF to the reader to try to figure it out? Figure out a pareto score and sort by it so it's at least in a reasonable order?
