Overall: Nice work. I don't see a problem with using the diagram, although I'm not sure if something other than an image/video file has ever gone into the image slot before. But for now it looks good. Epicgenius (talk) 14:08, 17 February 2022 (UTC)[reply]

Sorry, Bilorv, but I gotta be able to fit the file in {{main page image/DYK}}, most bots rely on a consistent image template format—could you put it in an image file for me? theleekycauldron (talk • contribs) (she/they) 09:15, 21 February 2022 (UTC)[reply]
