By Matt Stiles | | Topics: Policy & Politics

Since I get the day off, I figured I should repay our presidents by honoring their birthplaces with two maps made with Google Fusion Tables. This first map places points on their home towns (see larger interactive version): 

Here’s the same data but aggregated by state and mapped with polygons. Darker shades represent more presidents (see larger interactive version):

Mapping London Riots, ‘Deprivation’

By Matt Stiles | | Topics: Uncategorized

This interactive map, made with Google Fusion Tables, shows recent riot locations in greater London as red points. The colors represent “indices of deprivation” by “lower super output areas,” which appear similar to blocks or tracts in the U.S. Census. Deeper reds represent higher poverty, while blues represent more income.

UMBC professor Lou Paladino made this interesting map that visualizes academic performance by Washington, D.C., school districts.

World Internet Stats

The U.S. is among the most wired countries in the world, with three out of every four Americans having access to the Internet, according to these stats. Only Japan, Germany and the United Kingdom have higher rates of Internet use. 

This charts shows the top 25 most populous countries in the world, and plots the percentage of Internet users on the x axis (bottom), and the population of total Internet users on the y axis (left).

The U.S. is the orange dot. Notice that China, which has about 450 million users, still lags behind other counties in penetration rate. It’s the large dot at the top middle. So does India, the larger dot at the bottom left. (See an interactive version): 

Here’s the view as a map (see an interactive version): 

BTW: Iceland has the highest Internet penetration (98 percent). East Timor has the lowest rate (.2 percent).
