Well, draw.arc is specified by center, radius and start/finish angles, so it would be a lot of calculation to get these from the two points that must be joined on the circumference. I would probably translate this into the Postscript arct command, as you would probably have to use the Postscript or similar device to get a decent image. I programmed something similar, but a lot simpler, some years ago in Postscript and it worked out pretty well. Getting the correct angle for the text was tricky, you can see how some of the text on the example is upside down.

I don't know of a base graphics equivalent (xspline() might come close) so it might be best to opt for Grid. I'd just make circular arcs with sines and cosines. Of course the plot is a massive waste of space on a practical level. Long names will squeeze the adjacency data into a smaller and smaller area, making it harder to work out what is going on. I wouldn't want to use this for anything else - but hey, that's what art is for :) Playing with this (before the Kolkata Knight Riders' innings just started) and I hit a problem. You can't call strheight(X) to get the text height without first doing plot.new, but you don't know how big your plot is going to be until you know strheight(X). I'm sure there's a way round this, but... Chris Gayle is batting.
