Thanks to @datavisfriendly.bsky.social for highlighting some fantastic reproductions of Dr John Snow's iconic map of cholera spread (+ our own tongue in cheek homage to maps/arcade gaming), all submitted to our 2023 #map #competition. Check out the winners here: johnsnowsociety.org/2023/10/20/w...

#datavis @anychart.com, on their Data Viz Weekly caught my eye with this lovely depiction of Gender views in Europe by Teresa Talò The pattern is so clear, color scale nicely muted. I wondered what spatial analysis could do here to show something of an overlaid visual summary. Arrows? contours?

Today we're celebrating the Birthday of (the man, the myth, etc) Dr John Snow MD! This year's artwork is more than (just) stream of consciousness musings of a godchild of the social media team - each has real significance; our move to bluesky, birthday hat... and prizes for guesses re the others.

Happy (early) Birthday to the father of Field Epidemiology! John Snow, who turns 213 on March 15th, is legendary for using disease mapping to determine the source of the London cholera outbreak in 1854. #JohnSnow #Epidemiology

Despite increasing use of observational data in public health, researchers are still hesitant to use strong causal language (for fear of overpromising). New paper and comment in @bmj.com sets out new guidance on appropriate use/misuse of causal language www.bmj.com/content/392/...

Despite the 19th century discovery of the mode of transmission of cholera and the rapid evolution of its prevention and treatment, it still remains a problem today. More than 16,000 new cases recorded in early 2026, mostly in Africa. www.who.int/publications...

Thomas Wakley, the original editor of @thelancet.com was indeed no friend of Dr John Snow. In happier news, the journal published a 'corrected' obituary in 2013: www.thelancet.com/journals/lan... We're glad you had a refreshing visit to the John Snow pub @pwgtennant.bsky.social‬ 😊
