This diagram plots the similarity of pericopes (sections) in the New Testament based on their linguistic similarity in Greek:
Blue = Gospels, Purple = Acts, Green = Paul’s Epistles, Red = General Epistles, Gray = Revelation

Do we actually learn anything from this kind of diagram? The most interesting part to me is how the gospels on the right flow primarily through the Gospel of John to the epistles on the left. I wonder why that is.
Methodology
I calculated the cosine similarity between the full text of the pericopes using the Greek lemmas (after removing about forty stopwords). The pericope titles come from the ESV. I produced the diagram with Cytoscape. The widget at the top of the post comes from zoom.it, Microsoft’s Deep-Zoom-as-a-Service.
Bill Mounce’s excellent free New Testament Greek dictionary served as the source of the lemmas.
