British physician John Snow used a Voronoi diagram in 1854 to illustrate how the majority of people who died in the Broad Street cholera outbreak lived closer to the infected Broad Street pump than to any other water pump.
Briti füüsik John Snow kasutas Voronoi diagrammi 1854. aastal illustreerimaks, kuidas enamik inimestest, kes surid Soho koolera epideemiasse, elasid lähemal Broad Streeti pumbale kui mistahes teisele veepumbale.
