I implemented a new feature to the Interactive Diagram: you can now also load games into it. The game record that is displayed in the 'AI bar' (which can be opened by clicking on the 'Play It!' link) below the navigation buttons is now editable. If a game record is pasted there, it becomes the current game, through which you can step using the buttons. This feature is still in the alpha testing phase; the design goal was mainly to make it understand its own game notation. So that people who played a game against the Diagram in an article can post their game as a comment, and others can then copy-paste it in the Diagram to use the latter as a game viewer. (This was an idea suggested by Fergus.)
E.g. in the Capablanca Chess diagram of this article you can now paste the game:
The Diagram uses Standard Algebraic Notation for the games. Interpreting that is not trivial, so there could still be errors. There should be alert popups when it encounters moves it cannot understand (e.g. because the mentioned piece is not present, or because multiple moves satisfy the notation). Especially moves with implied side effects (such as e.p. capture) are tricky; if no pseudo-legal move matches the notation as given, but there is a single move that matches what is given, but has additional non-mentioned locust capture or promotion, it assumes that move was meant. It should also accept non-pseudo-legal moves that are unambiguously specified (e.g. by fully mentioning the origin square, or by mentioning the moved piece type when only one piece of that type is on the board).
Note that the loading of the game is only triggered by pasting it; if you type moves there, they will be ignored.
Also note that drag & drop moving of the pieces in the Diagram is now fully supported: the dragged piece is animated (a feature that was lost when I switched to using the piece images as background, to make room for foreground marker symbols), and the piece disappears from the origin square while you are dragging it.
