Defined in: kit/src/geojson.ts:157

const layer = globe.addRenderableLayer('Airports');
await loadGeoJson(globe.worldWind, '/airports.geojson', layer, {
  style: ({ properties, geometryType }) =>
    geometryType === 'Point'
      ? { point: { pushpin: properties.busy ? 'orange' : 'white', labelProperty: 'name' } }
      : { polygon: { fill: 'rgba(251, 191, 36, 0.15)', stroke: '#fbbf24' } },
