I wanted to do something like this for a long time, and finally I think it’s at a point where I can release this into the wild.
We’ll take a look at more than 2 million games, taken from the MillionBase PGN database. I ignored any Chess960 games contained, but in total there are 2,197,113 games. I was interested to see what kind of visualizations I can do, and what patterns would be revealed by considering so many games.
So - okay, simple enough, 100% width/height canvas at the background, put out some randomly placed dots, then link the dots depending on the distance.
