We're already in an Observable notebook, which makes our visual really easy to share! Share the link with your comrade and ask for comments - they could even jump in and fork your visual if helpful.

The second link doesn't work for me: https://observablehq.com/@wattenberger/exploration-hierarchical Maybe it has non-public settings?

Ah, thanks for flagging! I hadn't published it yet!

Works now. Thx for fixing. Also thanks for great presentations. Super useful to learn the general process...

thanks for the kind words! I learned a ton about Observable in the process that I'm excited to try out!
