Via Daring Fireball: Fighting Fantasy, the gamebook-style line of Choose Your Own Adventure books, has been flowcharted by fans into some massive directed graphs. The linked site covers some more minor series as well, along with a couple of classic Choose Your Own Adventure books—including, of course, the ever-chartable The Cave of Time (requires a real browser).

Update

Note that the flowchart site has moved from the link given at Daring Fireball (and that he’d also mentioned these books the day before); the links above have been corrected.
