I should have mentioned this earlier but I was thinking of archive.org's calendar view. Example: https://web.archive.org/web/20220000000000*/cnn.com

At the top you can see a timeline view with vertical intensity bars that can be clicked to go into a specific date range. I could see a possibility where instead of the number of snapshots of a site, it would be the number of bookmarks in the date range.

They also do something interesting with their day display just below. Instead of changing opacity the size of the bubbles around the dates expand based on the number of snapshots. In the case of bookmarks, I would think it should be possible to calculate the size of the bubbles once, and only recalculate if a bookmark gets deleted. Hopefully this would keep the GUI responsive.

Thank you again for building this!
