SO is giving me a hint that questions with similar titles have frequently been closed, but I cannot find an answer. Lately I have seen the following diagram on Bloomberg a lot, especially in representing Import/Export volumes:
Is it possible to get something like this in R? If yes, what package is used?
As soon as I figure out the name of the plot I will update the title so that it'll describe the question more accurately.
Update - apparently, the name is chord diagram.
