My TopoJSON object contains 3 polygonal sub-objects of which the first D2P1 appears with the geometry correctly drawn on the OSM map, but the other 2 polygons D2P2 and D2P3 are drawn distorted on the map turning into projected lines instead of their! correct geometry.
Could you help me to write my code correctly so that my 3 polygons appear correctly configured?
