Great work @TomNicholas!

For rich/html reprs, I think that we could take much inspiration from some of the dask reprs shown in this blog post.

I haven't looked at your repository in detail yet, but I have one general question about the design: what is the rationale of having two separate classes DataTree and DataNode? Could those classes be merged somehow? To me it seems that any node could be the root of a (sub)tree. h5py has a separate File object that does double duty as the HDF5 root group, and serves as entry point into the file, but in the case of Xarray maybe this is less relevant since Xarray object are abstract data containers? Zarr (abstract data store) has no such separate class and uses a regular zarr.hierarchy.Group as the root.

FWIW, a while ago I wrote a mock-up (and probably outdated) DatasetNode class:
