In addition to experimenting with new visualization techniques, Sebastian produced an improved version of the “Top 5 Terms” chart:

Clearer and less visually cluttered, this version makes it easier to distinguish which terms were used most frequently by each author within each document.

Particularly engaging is the 3D interactive force network diagram he produced using the network3D R-to-JavaScript library. It features correlations of 0.4 and higher, and you can interact with the nodes, rotating them to bring a particular work into focus while highlighting the connections between texts.  Based on this degree of interdependence, it’s interesting to see Clara Zetkin as an outlier, only connected to Georgi Plekhanov.

Please take a moment to visit and explore the diagram, and let us know what you think.
