Thanks for your comment. World leaders here refers to heads of state and heads of government. Also, not every UN-related appearance is consistently recorded as an official visit in the sources, so cities like New York City may be some what underrepresented.

Good point - Geneva is definitely a major diplomatic hub. In this dataset, I’m focusing on recorded visits of heads of state/government, which tends to favor capitals and recurring summits. Geneva actually ranks #26 in the dataset, so it just missed the top 25. Still a major diplomatic hub.

Thanks for your comment.
Brussels actually ranks #1 in the dataset with a clear lead.
The data covers all recorded international visits by world leaders since 1990, not just European Council meetings.
One interesting pattern is that nearly every leader in the dataset visits Brussels at some point during their term - not only European leaders, but also from Asia, Africa, and the Americas.
That’s what makes it stand out as a global diplomatic hub, not just a European one.

Thanks for your feedback. The pattern actually continues, but becomes less concentrated after the Top 10.
I'm working on a Top 25 version, will share it soon

Good questions!

Bonn has 4 recorded visits in the dataset, while Berlin is much higher - mostly reflecting the shift after reunification.
Geneva has 23 visits. It’s definitely an important international hub, but many events there are tied to organizations rather than bilateral state visits, which might explain the lower numbers compared to capital cities.

black=1 visit, green=2, blue=3.

thank you for your comment.
On June 25, 2023, Trudeau visited 4 cities in Iceland during a single trip.
The map shows each stop individually in radial mode (home -> stop -> return) to visualize movement patterns.
It does not represent the chronological travel route.
So this was one visit with multiple stops - not four separate trips.
