Visualizing Twitter Network with a Chord Diagram
In this workflow, we will:
Use the Table Reader node to read the dataset listing tweets with hashtag #KNIME between end of July 2021-beginning of August 2021 (1 week).
Filter the data using the Row Filter node and then aggregate the data to get the number of retweets between every pair of users in both directions using the GroupBy node.
Apply Cross Joiner and Pivoting nodes 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.
Visualize the connections using a Network Viewer node.
