This document discusses data visualization projects at Twitter. It describes an interactive visualization called Laika that showed geolocated Twitter activity during the 2012 European football tournament with over 1.6 million tweets. The visualization allowed users to get an overview and then zoom in and filter tweets. It also featured day/night modes and blending techniques to render tweets on a globe with halo effects indicating locations.
