This shows only the headings of the 5 categories and then empty bars on Firefox... could you offer a pdf or picture as an alternative download for people who don't use (I suppose) Google Chrome?
You may be blocking the javascript needed for this page to render properly. I'm on Firefox 92.0.1, saw what you saw at first, then in uMatrix I enabled "script" coming from "code.jquery.com". Page renders fine now.
