Data visualization heat map

Interactive population density heat map gives users an overview about population density in different parts of the world or within a country. With the help of heat map, users can understand more about the population distribution.

Here is an example interactive population map of United States, the region with the largest population (i.e., California) is displayed in red and Wyoming with the lowest population shows grey, while those in between are shown with colors that lie in between the two extreme colors. Place a mouseover on the WA, CA, CO, PA or NY for details.
