For rich/html reprs, I think that we could take much inspiration from some of the dask reprs shown in this [blog post](https://blog.dask.org/2021/08/23/gsoc-2021-project).

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](https://docs.h5py.org/en/stable/high/group.html), 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](https://zarr.readthedocs.io/en/stable/tutorial.html#groups).
