This visualization was developed in this notebook on Observable. That the notebook is public so that anyone can see it and this webpage depends upon that notebook. In contrast, the other two maps that I've built for DAAC are built with private notebooks and served independently of Observable. While this distinction is probably indiscernible for the user, it's quite important for the developer so I wanted to mention it. I chose to serve this one with the public notebook since all the data is open.
