Could move these to an "Appendix" at the end so it doesn't disrupt the notebook text.

Could make this a link with more descriptive text and description, like "Visit the [Project Dataset](https://observablehq.com/d/caa07ad98b53d325) notebook for more details about this dataset and the processing performed."

I think you are missing the "notable feedback" that you received for the prototypes.

Love the lens interactivity. Does appear to be 2 tooltips showing up though? Making the bubbles bigger is a fun effect, helps a *little bit* with navigation. This might be one to consider linked views with? One overall and one zoomed-in view (could be another scatterplot, table, etc.).

Ooo, sorting and brushing! Nice!

I feel like if you linked this visualization with your scatterplot, you'd have something really neat!
