How to use the d3-geo.geoRotation function in d3-geo

length = d3Geo.geoLength(sampleExtendedGeometryCollection);
length = d3Geo.geoLength(sampleFeature);
length = d3Geo.geoLength(sampleExtendedFeature1);
length = d3Geo.geoLength(sampleExtendedFeature2);
length = d3Geo.geoLength(sampleFeatureCollection);
length = d3Geo.geoLength(sampleExtendedFeatureCollection);

// geoInterpolate(...) ====================================================

const interpolateFct: (t: number) => [number, number] = d3Geo.geoInterpolate([54, 2], [53, 1]);

// geoRotation(...) =======================================================

// create rotation -----------------------------------------------------

const rotation: d3Geo.GeoRotation = d3Geo.geoRotation([90, 45]);
const rotation2: d3Geo.GeoRotation = d3Geo.geoRotation([90, 45, 27.5]);

// use rotation --------------------------------------------------------

const point: [number, number] = rotation([54, 2]);
const inverted: [number, number] = rotation.invert([54, 2]);
