It is recommended to use GeoJSON format data for geometry layer data.

// Pass in GeoJSON type data *** L7 supports it by default and does not require parser analysis
const data = {
  type: 'FeatureCollection',
  features: [
    {
      type: 'Feature',
      properties: {},
      geometry: {
        type: 'Polygon',
        coordinates: [
          [
