Each player's cell is the part of the pitch nearer him than any other player; the description gives each team's share.
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 players = Array.from({ length: 22 }, (_, i) => ({ x: 8 + ((i * 37 + (i < 11 ? 3 : 17)) % 88), y: 8 + ((i * 53 + (i < 11 ? 5 : 11)) % 84), team: i < 11 ? "home" : "away", number: (i % 11) + 1 }));
const svg = drawKyogijo({ sport: "soccer", layers: [{ kind: "voronoi", from: "opta", data: players }] });
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.
