Infographic of the Day: A joint team of researchers from Northeastern and Harvard have compiled a nifty visualization reflecting the ever-changing mood of Americans by state over the course of a given day based on the tweets they send out.

Not only did they analyze the sentiments we collectively expressed in 300 million tweets over three years against a scholarly word list; these researchers also mashed up that data with information from the U.S. Census Bureau, the Google Maps API and more. What they ended up with was a fascinating visualization showing the pulse of our nation, our very moods as they fluctuate over time.

Props to NY for having a perpetual sourpuss.
