here's how you scroll http://bost.ocks.org/mike/scroll/
i want to do also nyc and sf.
I'm only using tweets on which users chose to publish their locaiton, so it isn't all of the tweets, but a good chunk of them.
I chose red and blue because they're quite perceptually separated, so it's easy to point them out on the map.
I've built a map that takes a geofenced stream of tweets and runs AFINN-111 sentiment analysis on them, and then displays them in real time on a map of London.
Negative sentiments are displayed as Red tweets, happy tweets are Blue.
The whole thing is built on node.js using node-tweet-stream, node-sentiment and socket.io. The frontend map is leaflet with stamen design's Toner tiles.
It's quite fun to watch, especially when there's a football match or a concert. If you click on the "follow tweets" checkbox, new tweets pop up as they arrive, although currently that makes the map pan north.
Thanks!
Dario.
