conduit diff tree viewer (jupyter?)

Conduit's diff trees provide a lot of info. For larger diffs, it would be really nice to have a viewer that organizes the info to make it easy to digest.

We could use jupyter or fancy text, hatchet trees (https://github.com/hatchet/hatchet) might be a good inspiration -- however the conduit diff trees contain different info.

The issue names no files, tests, or entry points; first inspect how Conduit diff trees are produced and represented. A completed change would provide a viewer that makes larger diff trees easier to digest, with the presentation approach and scope clarified between Jupyter and text output.
