These are four charts containing statistics about tweets from the Austin area.
The charts discuss a sentiment analysis of the tweets and when the tweets were sent. Red means the tweet was catagorized as positive (for example: What a great day), blue as negative, and green as neutral. The last chart contains the 50 most common words used in the tweets.
I think the results are pretty interesting to see, but if you're interested in a TLDR: People tweet sad things on weekdays and happy things on weekends, and tweet sad things late at night and happy things in the afternoon and evening.
