Tracing diffusion events
Whisper traced the diffusion story about a recent 6.8 magnitude earthquake, and a series of aftershocks and tsunamis hit the northern coast of Hokkaido island. As shown in the picture, original tweets are placed at the center of a circle, and pathways are created to connect to geo-groups once the tweets got re-broadcasted (retweeted) by the groups. The retweeting activity is shown as a sequence of color-coded retweet glyphs moving along pathways indicating the timing and sentiments of the retweets.
