That's a really cool visualization. Do you know if anything like this exists for the European grid?

Not as cool a visualization, but https://www.swissgrid.ch/swissgrid/de/home/reliability/wam.h... shows the frequencies and phase differences (in degrees) between a few measuring stations around Europe. The phase difference between Switzerland and Spain is now some 50°, which is actually much larger than I would imagine these differences becoming.

All power grids are connected, so there is just one frequency.

Aren't all the grids in US/Canada also connected? My understanding was that they are all connected and that the grandparent visualization was showing the frequency differences across major portions of the US/Canada grid. Or am I getting this wrong?

No, they are not. There are four major grids: West, East, Quebec and Texas. Each one is referred to as an "interconnection". Synchronism is maintained within each interconnection, and they may have non-synchronous (i.e. DC) links between each other. Here is a map:
