Hey Danes! We just put together a comprehensive (and beautiful) visualization of mobility during the COVID-19 crisis. This thing is amazing, and I'll explain why in the thread. 
Well, for a start, the data set is insane. It's transitions between municipalities from all Danish operators. Let me say that again: ALL the operators. That means that every trip is included. (And it's just transitions, no individual trajectories were used, so no privacy issues)
Secondly the visualization itself is a rare beauty, hand crafted for you by @ulfaslak. So in spite of containing lots of data it's super fast & responsive. Using the brush, you can choose which period to display. Anything from a single day to the entire period.
When you click on a municipality, you can see all trips to/from the rest of the country. Below, I've selected Aarhus.
And you can scale/normalize the data in many different ways. So in addition to raw counts, you can visualize according to square root and log, and normalize by population or area. That way you can explore out hard-to-see patterns. (Below is log-scaled version of image above)
Ahahhaha. *I forgot the link*! It's here: covid19.compute.dtu.dk/visualizations…
And a picture of baby yoda to say I'm very sorry for that (crucial) omission:
