Forgive me for a shameless plug. I've been playing around with public data and putting visualizations on the on my website:

https://bibledatalab.com

Attached is one such visualization of over a dozen. This one shows the density of hapax legomena in each of the New Testament books. I've done a few visualizations with morphology, frequent words, rare words, New Testament manuscripts, manuscript edits especially on Sinaiticus. I'd love for you to check it out and let me know what I should change and what other investigations / visualizations you'd like to see!
