Furuti 1
A polyhedral globe projection maps the Earth onto a cube's six faces, each rendered as a light blue patch. The map shows country polygons in gray and a graticule, all projected using `d3.geoPolyhedralFuruti1`, a custom projection built with `d3.geoProjection`, `d3.geoGnomonic`, and `d3.geoPolygon`. The example imports the `d3` library, loads `countries.geo.json`, and uses `d3.geoPath` to draw SVG paths.

Based on "Earth in a Cube" by Enrico Spinielli and on my research for d3-geo-projection/pull/86 and d3-geo/issues/46.
Re-incorporating Jason Davies’ clipPolygon() code into d3v4.
Code base at Fil/d3-geo:clip-polygon.
