“The real innovation lay in the data that generated that diagram, and in the investigation that compiled the data in the first place. Snow’s Broad Street map was a bird’s-eye view, but it was drawn from true street-level knowledge” (Johnson, 2006, p. 273). What was on the map itself wasn’t nearly as important to history as what went into gathering the information to make the map. “Snow’s map—with Whitehead’s local knowledge animating it—was something else entirely: a neighborhood representing itself, turning its own patterns into a deeper truth by plotting them on a map...a brilliant work of information design and epidemiology, no doubt. But it is also an emblem of a certain kind of community” (Johnson, 2006, p. 273). Although Snow’s map was unable to influence the leaders of his time, it definitely influenced the world on a larger …show more content…

Especially, since the cure to lethal diseases is often rather simple-- “cholera has a shockingly sensible and low-tech cure: water” (Johnson, 2006, p. 74). We live in a world where clean water is a basic human right for people of a developed society, but a blessing--and perhaps difference between life and death-- for those of a developing society. If something can easily be improved, why not improve
