Maybe you remember <http://www.textarc.org>, which creates an interactive representation of relationships within a text.
Textarc doesn't work for me on OS X any more, but I did find a JavaScript recreation, <http://vallandingham.me/textarc/> (code: <https://github.com/vlandham/textarc>). I'd like to try recreating and maybe extending it in Jupyter Notebook. Is anyone else interested in working on this as a project (for fun)? I'm pretty new to Notebook, so it will definitely be a learning project for me. I'm interested in using programs to explore texts generally. Here's a re-creation of Ulises Carrión's "Hamlet, for two voices" in Python: <https://gist.github.com/evildmp/b114ae9fa0e998958e6f>. Daniele -- https://mail.python.org/mailman/listinfo/python-list
