John Snow's Dot Map

Origin
John Snow was a physician who promoted the practice of anesthesia and hygiene and is considered the founder of epidemiology, the study of the cause and spread of diseases.

When a cholera outbreak happened in Soho, London in 1854, it infected and killed six Warehouse 12 agents. The Warehouse then contacted Snow, who found the source and helped change the water system in London and other cities. The dot map, along with his pump handle, were some of the few artifacts voluntarily given to the Warehouse.

Effects
Animates to show the epicenter and spread of contagions such as disease and pollutants. The user will be in contact with small particles of the disease while in use, running the risk of becoming infected.
