This looks great! Thanks for the contribution. Just a few minor nits.

• Could we update the Overview section to something like:
  This notebook will demonstrate how to use Kerchunk with hvPlot and Datashader to lazily visualize a reference dataset in a streaming fashion.

• In some of the other case studies, there is a section that gives a bit of background on what dataset we are using. It might be nice to give a tiny background about the Climatology lab's gridMet dataset and add any attribution they might have/request.

Overall awesome example! It'll be great to add it to the cookbook.
