This graphic is almost useless since the references are tied to a particular layout of references. In the future, some or many of the primary refs will be replaced by more general sources, per guidance by WP:SECONDARY and WP:TERTIARY. Also the inclusion of words interferes with the dissemination to other languages. Simpler schemes with one or fewer reactions would be more helpful for Wikipedia.-- Smokefoot ( talk) 16:39, 20 July 2021 (UTC) reply
