Cool idea! Just some feedback: 1. Bug; I was able to enter just spaces as a search character somehow 2. Maybe have an example query at the beginning, as it's not clear what this does. 3. The graphs look cool, but what are the units on the y axis? What are Sentiment units? 4. It would be cool if the query was in the url, so I could share the link! Anyway, loved the idea and the sire looks pretty well done
