Imagine you are a virus like H1N1 or Ebola. You decide to take a trip and infect others to create an epidemic. Where would you travel? Scientists have built data mapping software to predict the paths epidemics will take across the globe. The resulting maps are beautiful and complex. Many are currently on display at the New York Hall of Science.
