seasonsSvgfunction

The seasons sheet: the Sun in the middle, the Earth's orbit as a ring, and the Earth at four points of it (March, June, September and December), each with its tilt, the dark half hatched, the season of the northern half named, and three facts. The axis leans the same way at all four, so in June the north leans toward the Sun and in December away from it.
