A Visual Exploration of Twitter Streams II

After my first shot at analyzing Twitter data visually I received a lot of great feedback. Thank you!

For my new attempt, I worked on incorporating your feedback such as: filter unrealistic location changes, show connections “grow” instead of just popping up and zoom to an interesting location. The new animation therefore focuses on Manhattan – one of the places with reasonably high geotweet coverage.

The background is based on OpenStreetMap coastline data which I downloaded using QGIS OSM plugin and rendered in pyprocessing together with the geotweets. To really see what’s going on, switch to HD resolution and full screen:

It’s pretty much work-in-progress. The animation shows similar chaotic patterns seen in other’s attempts at animating tweets. To me, the distribution of tweets looks reasonable and many of the connection lines seem to actually coincide with the bridges spanning to and from Manhattan.

This work is an attempt at discovering the potential of Twitter data and at the same time learning some pyprocessing which will certainly be useful for many future tasks. The next logical step seems to be to add information about interactions between users and/or to look at the message content. Another interesting task would be to add interactivity to the visualization.
