Levenshtein SVG

[Addsamuels]

After many failed attempts, I've got a SVG of the Levenshtein distances of words in the MS 408 (although the code was crafted by AI, so it could be completely inaccurate)

Enjoy.

I don't know what this is supposed to be. The topmost word in this image appears to be "okalchdaralcharaiin". Is this expected? I wasn't sure this word existed in the MS, but after I removed the spaces, I've found it, yay!

Code:

oshfdk> cat zl.txt | perl -pe "s/[.,]//g" | perl -pe "s/\[(.*?):.*?\]/\1/g" | grep "okalchdaralcharaiin" <f108r24+P0>    <%>folaiin{c'hkh}yqokallkedyqotedyqokedqotedyokalchdaralcharaiin

The original line is:
<f108r.24,+P0>    <%>folaiin.{c'hkh}y.qokal.lkedy.qotedy.qoked.qotedy.okal,chdar,al,char,aiin

So, it looks like comma-spaces have been removed in preprocessing.

What are the axes of this image?
