Calculate the betweenness scores
Betweenness centrality represents the degree to which nodes stand between each other.
In a retweet network, a user with a high betweenness centrality score would have more control over the network because more information will pass through the user.
Can you identify users who are central to people who retweet the most and those whose tweets are retweeted frequently?

The library igraph has been pre-loaded for this exercise.
