This looks very interesting on first try, I'll take more of a look when I'm on a decent screen.

Can you at the moment, or would it be possible to show a position score calculation at each point? Obviously that is going to be time intensive if the scores are not already available in your source data, but it might be a useful addition as an option at any point. Explanatory comments also - where available - would be nice.

Excellent work, good luck.

Thanks for the feedback. I like the idea of adding position evaluations. Perhaps we could do this with a precomputed pass over the dataset, or possibly do a shallow analysis in the browser using a js port of stockfish, though this is probably not the best option.
