Tree visualizations of chess openings
The first thing that strikes you when learning chess opening theory is volume. Modern theory is so broad that variations increase exponentially with the number of moves. You can get a sense of this by reading any [opening book](https://lichess.org/opening) and trying to memorize as many lines as possible.
