Graph of subreddits that have COVID 19 vaccine-related posts. The largest subgraph above shows subreddits that have COVID-19 vaccine-related posts. Node sizes represent subreddit user sizes, node edges indicate shared COVID-19 vaccine posts between subreddits, and node labels indicate the subreddit name. Node color is based on centrality (red is higher centrality, yellow is lower centrality). Edge direction was based on whether a node had >50% of its posts prior to its adjacent connecting node e.g. A- >B if >50% of A’s shared posts were made before B. We used larger labels for subreddit nodes with >5,000 COVID-19 vaccine posts
