Die 1-Billionen-Dollar-Volkswirtschaften der Welt im Jahr 2025

Pretty sure this is 2024, Switzerland and Poland reached 1 trillion in 2025.

And why rest of UK is not blue?

Since subdivisions are arbitrary, it would be more informative to eg. group Kanto or Padanian counties till they reach the trillion and then to erase/not show the rest of county borders in respective countries
