The picture above was drawn when the docs were built. The script below draws it again with the published package.
import { drawMulti } from "@johnmorrisdotca/kyogijo-stadiums/multi";
const svg = drawMulti({ preset: "judo-1x3", language: "ja", sample: 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 0.64.0.
