The Interactive Diagram Tag

Description

Thanks to H. G. Muller, several pages on this site have an Interactive Diagram. This diagram lets you view movement diagrams, see legal moves of pieces you click on, and even play the game against a computerized opponent. His Play-test applet for chess variants provides a Wizard that can generate an Interactive Diagram for you. The HTML code for an Interactive Diagram will run a JavaScript script, such as betza.js, and have some variable assignments in a DIV with the class of idiagram. If you know what you're doing, you can create one by hand and use an alternative script, such as betzaNew.js or Fergus Duniho's fork, betzaFlex.js.
