cyoa: "In scanning over the distribution of colors in this plot, one clear pattern is a the gradual decline in the number of endings. The earliest books (in the top row) are awash in reds and oranges, with a healthy number of ‘winning’ endings mixed in. Later cyoa books tended to favor a single ‘best’ ending (see CYOA 44 & 53). The most extreme case of this was actually not a Choose Your Own Adventure book at all but a gamebook offshoot of the Zork text adventure series. The Cavern of Doom (labeled WDIDN 3 above) has a virtually linear progression where endings later in the book are increasingly better than those on earlier pages. This is reflected in the nearly unbroken spectrum from red to blue when scanning down the rows."
