Watch how the measles outbreak spreads when kids get vaccinated – and when they don't

This Guardian's animated visualization allows users to understand how measles spreads once someone gets infected. The visualization also shows how different rates of vaccination protect (or don’t) a community. The animation shows red dots, which represent contact with an infected person, approaching groups with different rates of vaccinated elements and shows how the disease spreads infecting elements that are susceptible, either because they weren't vaccinated or because even though they were vaccinated they were still susceptible.
