A visualisation of a week’s worth of geocoded tweets that were all in or around Greater London.
It’s a fairly simple Processing app, displaying each tweet in order. The ellipses displayed at each point though stay for 5 seconds, getting gradually smaller and darker with each second. The best way I could think to do that was with a fading point class for each tweet. This is then poked every second to both update, and then return whether it should be removed from the stack of points or not.
Playing around with this also reminded me how to sort an ArrayList. My Java knowledge is slowly returning..
