Example:

import { PolygonGenerator, PolygonFormat } from "polygons-generator";

const polygonGenerator = new PolygonGenerator({
  format: PolygonFormat.GeoJSON,
});

const lat = 51.46298;
const lon = -0.05939;
const radiusKm = 1;
const numberOfPoints = 10;
const res = polygonGenerator.generate(lat, lon, radiusKm, numberOfPoints);
console.log(JSON.stringify(res, null, 2));
