You need some visual feedback that it's loading. I see a blank screen for 30 seconds.

This is really nicely done, the log zoom makes 4M events feel navigable instead of like a wall. How are you serving a viewport at that scale: precomputed levels of detail, or a query against the raw events on each pan and zoom?

I think you need to check these. I saw one item (a bank maybe?) that was started on "20141221" or something. Didn't get parsed so it is treated as the year 20241221, not 2024.
So many examples of this right off the bat. This needs some serious work/testing.
