With the four tassels

Green east, red south, white west, black north.

Sumo dohyōDrawn as: a sumo dohyō: a clay square of 6.7 metres, 55 centimetres high, with a ring of 4.55 metres made of 20 tawara, the sand of the jano-me and the two shikiri-sen. The four tassels of the roof are in the colours of the quarters: green east, red south, white west, black north.

The picture above was drawn when the docs were built. The script below draws it again with the published package.

import { drawKyogijo } from "@johnmorrisdotca/kyogijo-stadiums";

const svg = drawKyogijo({ sport: "sumo", budo: { tassels: true } });

This page imports the package from jsDelivr (major version 0), which serves only versions that have been published to npm. A feature added after the last release is not in it: the page then keeps the picture above and says why. The docs were built from version 0.6.1.
