If you’ve been following the news about the shooting of 18-year-old Michael Brown in Ferguson, Mo. and the resulting standoff between police and crowds of protesters and mourners, you know that Twitter has played a key role in spreading the news of the unrest (along with YouTube, Instagram and other social platforms). Twitter’s head of data science Simon Rogers pulled all of the geo-tagged tweets that mentioned Ferguson and used the CartoDB tool to create an interactive map that shows how awareness of the violence in Ferguson spread throughout the network.
