Prism Map

This is a prism map representing West Nile Virus cases in the United States. This type of map is nice cause it allows for easy assumptions to be made when one looks at it. It uses colors to indicating number of cases but also uses the height of the states to indicate which has more cases. This map also shows that the misconception that gulf states were the most vulnerable it was in fact the upper midwestern states that were at most risk.
