The picture above was drawn when the docs were built. The script below draws it again with the published package.
import { fieldMarks } from "@johnmorrisdotca/kyogijo-stadiums/athletics";
const jumps = [{ athlete: "B", distance: 8.1 }, { athlete: "B", distance: 8.46, across: 0.3 }, { athlete: "B", distance: 8.28, across: -0.2 }];
const svg = fieldMarks("long-jump", jumps, { surface: { athletics: { layout: "long-jump" } }, labels: true }).draw();
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.
