Below is a tool to navigate almost two years of tracking sentiment (emotion) from Twitter users across all nation states as they discuss foreign nations. Details of the approach are here.
How to use it. The map tracks two clicks at a time. Click once on a country to see its attitude toward the rest of the world. The intensity of green indicates more positive feelings, and red indicates more negative. Click a second country to show the timelines of sentiment between your first country and your second. To reset with a new country, click a third country.
