R-Ladies global tour

It was recently brought to my attention by Hannah Frick that there are now sooo many R-Ladies chapters around the world! R-Ladies is a world-wide organization to promote gender diversity in the R community, and I’m very grateful to be part of this community through which I met so many awesome ladies! Since we’re all connected, it has now happened quite a few times that R-Ladies gave talks at chapters outside of their hometowns. An R-Lady from Taiwan giving a talk in Madrid while on a trip in Europe and another one doing the same in Lisbon, an R-Lady from San Francisco presenting at the London and Barcelona chapters thanks to a conference on the continent, an R-Lady from Uruguay sharing her experience for the New York City and San Francisco chapters… It’s like rockstars tours!

Therefore we R-Ladies often joke about doing an exhaustive global tour. Hannah made me think about this tour again… If someone were to really visit all of the chapters, what would be the shortest itinerary? And could we do a cool gif with the results? These are the problems we solve here.
