Function geoPath

Build a GeoJSON → SVG path renderer using the given projection. Returns a function with .bounds() and .centroid() methods.

const proj = geoNaturalEarth1().fitSize([960, 500], featureCollection);
const path = geoPath(proj);
const d = path(feature);           // SVG path string
const [[x0,y0],[x1,y1]] = path.bounds(feature);  // bounding box
const [cx, cy] = path.centroid(feature);           // centroid
