Where we tested it
Dragon
TaskThe model's task was to draw a picture of a dragon as an SVG.
Three files worth 6, 3 and 3 points out of 50, the last three places among 34, and none of them looks like a dragon. It claimed it had checked the result in several browsers and a validator, even though the only tool it had failed every time.
You'll find the size band and figures for other models on the Tested models page.
