The thickness of the line would be better used to show the standard deviation of the sentiment score?

Mm, that's a good point. Still, I think there's value showing the magnitude of tweets about a candidate

Really can we we be any more obnoxious in pushing an agenda? I do not come to HN to read/see this tripe. The OPs slant is obvious just by the pictures selected, so will HN go this route as well?

Thanks.

how about including ben carson, ted cruz and few others?

On the way! Though probably just Cruz and Rubio...

How was this made? Looks great!

Click on the link on the top right of the page to see. C/P'd for convenience:

This graph shows the sentiment of tweets about Bernie, Hillary and Trump over time. The location of the line along the y-axis shows the average positivity (or negativity) of tweets about each candidate. The width of each line shows the volume of tweets (thicker line = more tweets). Sentiment analysis is done via Indico’s API, which is awesome. Tweets are streamed via Twitter’s Streaming API, because obviously. Built by Will Tachau

I'm curious how accurate the sentiment analysis is when dealing with sarcasm, which I suspect is especially popular in tweets about politicians.

Great work.

Thanks!
