The graph represents a depiction of messages containing moral and emotional language, and their retweet activity, across three political topics: gun control, same-sex marriage, and climate change. Nodes represent a user who sent a message, and edges (lines) represent a user retweeting another user. The two large communities were shaded based on the mean ideology of each respective community (blue represents a liberal mean, red represents a conservative mean).
