I visualize the the diffusion (retweet) of @ De gewa's tweet from 2012-2013.

The study revealed the dynamics of how common Chinese twitter users absorb and help rise the attention to the Tibetan civil movement.
Each node is a single Tweeter user. When a node sparks, it means the user perform a retweet action, which was visualized as signals fired by the user to his follower. The edges denoted the following-follower relationships. Those edges which fostered further retweets were highlighted.
Hence, over the time, important edges in the network would be marked by brightest colors.
