The bullet graph as designed by Stephen Few has few other elements that could be of use, like 'qualitative ranges' and 'symbol marker'. Just mentioning it...maybe it could be a useful addition. (Not for reproducing the referenced dataviz) In case I stated the obvious, no harm/criticism intended. See https://en.wikipedia.org/wiki/Bullet_graph

I've added a link, thank you for mentioning that the design includes more than just comparing two numbers!

strangely, this shows problems in reading covid.csv, but if I fork it it works...

Thanks for flagging! We're working on the outage https://twitter.com/observablehq/status/1783532329387827511
