Omnigraph is a visualization of positive and negative emotions through the USA, using the Instagram API.
Ominigraph uses the Instagram API and sentiment analysis to analyze captions in Instagram photos for any city in America. It employs a recursive algorithm that queries the API and, when provided enough data, provides how many positive, negative and neutral captions it found. This is shown through an interactive map built on top of D3.js.
Users can also zoom into a particular city and see the results more closely.
When entering the site, users are only shown the top 30 cities in the USA, but the can search for any city and see what the results for that city are.
