In this workflow we will: - Read the dataset listing tweets with hashtag #KNIME around the week of July 12, 2018 - Row filter and GroupBy to get the number of retweets between every pair of users in both directions - Cross Joiner and Pivoting to create a weighted adjacency matrix listing each pair of users in two different cells, one for each retweet direction - Visualize the connections in a chord diagram created by the d3 script in the Generic JavaScript View node
