Fig. 2: Vaccine and climate community networks exhibit distinct structure.
From: Debates about vaccines and climate change on social media networks: a study in contrasts

Network of communities formed by users tweeting 10 times or more in the climate change (top) and vaccine (bottom) conversations, for retweet (left) and mention (right) networks. Each node represents a community made up of two or more users. Edges represent interactions between the users: a member of one community has tweeted or mentioned a member of another community. The size of the node represents the size of the community, and the color of the node represents the most common sentiment of the users in each community: green represents pro-, red represents anti- and yellow represents neutral.
