Data library sources that are worth integrating with

Some of these may be proof of concept level at best while they are under our control, but good to keep many in mind to avoid overspecializing and painting ourselves into a corner:

- numpy arrays (or rather dictionaries of numpy arrays)
- pandas
- xarray
- dask
- tiled
- WrightTools (It's my graduate work, so useful as a test bed for integrations into libraries themselves)
- raw h5py
- Zarr
- functions
- web APIs
- databases
- networkx (graph data rather than array-like)

The issue lists possible integrations, including NumPy arrays, pandas, xarray, dask, tiled, WrightTools, h5py, Zarr, functions, web APIs, databases, and networkx, but names no files, tests, or entry points. Start by defining which source or sources are in scope and what integration behavior is required. Done is not specified beyond avoiding overspecialization and supporting useful data sources.
