I recently wrote a bibliometric paper using VOSviewer where I analyzed keyword clusters, and the logic here is exactly the same! In my analysis, certain keywords acted as hubs that bridged different research fields. It’s interesting to see that the same betweenness math I use in my own field can be used to map out a character’s social relationships.

This reminds me of how I often struggle to keep track of complex character relationships while reading. The connections frequently get tangled or blurry in my mind. Seeing them visualized like this provides a clear, 'at-a-glance' understanding!
