How do the English versions break the text into sections?

2 John Sanky Diagrams Section Headings
From https://www.openbible.info/labs/bible-section-sankeys/ 

Over at OpenBible.info, Stephen Smith continues to play with interesting visualizations of the biblical text. A recent post shows how we can see the way different English versions break up the text under section headings:Explore Bible Sections (Pericopes) with Sankey Diagrams. Using a free online resource, SankeyMATIC, Smith took twenty English Bible, generated the data for where each split up the text (he shares the data which looks like a lot of work to me), set it up to be used in SankeyMatic, and then generated Sankey Diagrams for each book of the Bible. I've copied the one he generated for 1 John. 

What are you looking at? Sankey diagrams provide a way of comparing and visualizing data. The height of the band indicates the number of sources in agreement. The splits show where they differ and how many differ. As you would expect, they all agree about the beginning and end of the text. Most versions insert a heading at 1.4, but at least a couple versions split at 1.5, and some make no split at all.

So, what good is this kind of information? Smith cites some examples from Ruth and Lamentations (acrostic divisions). 

Another way I think this kind of visualization could be helpful is to compare alignments in the LXX version of books as compared to the Hebrew. E.g., it's always messy trying to align ch:vs in LXX of Isaiah w/ that of the Hebrew (and English versions). Esther is also messy that way. And the Psalms need alignment between the Hebrew, Greek, and English with offsetting chapters and verses. 

These Sankey diagrams could also be helpful for showing some key places where sections are in question. For example, here is a snippet Smith generated for Mark 8.27-9.30.

Mark 8.27 starts the scene near Caesarea Philippi where Peter makes his confession of Jesus. Most versions make a split at 8.31 and the first Passion Pronouncement. Some break again at 8.34 when Jesus calls the crowd together and talks about what it means to follow him, but some don't break until 9.2. It appears that one version breaks at 9.1, though 9.1 really does belong with the preceding. (And unfortunately, the Revised Common Lectionary follows the chapter break rather than the logical break at 9.2.) The Transfiguration starts at 9.2. Should it run until 9.14, or, as some versions do, break at 9.9 and the discussion as they are coming down the mountain about rising from the dead and Elijah?

And thanks to Smith's sharing of the data, I will hope to find the time to plug in my preferred division of Mark's gospel and use the SankeyMATIC to show how mine differs from the others.

One other thing that might be interesting historically is to use Eusebius' Kephalia of the Gospels to show how it compares to modern divisions.

How else do you think these could be used?
