AlbersUSA Projection Fails for Coords of Puerto Rico

[BugsBunny338]

Hi there,

When running cat input.geojson | dirty-reproject --forward albersUsa > output.geojson on data/us-states.geojson, it works fine.

When I replace us-states.geojson with my custom file with coords inside of the US, it still works fine.

However when I supply my custom puerto-rico.geojson, it returns null values instead of valid coordinates.

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {
        "STATE_FIPS": "01"
      },
      "geometry": {
        "type": "Point",
        "coordinates": [
          -66.72280000,
          18.16380000
        ]
      }
    }
  ]
}

Another examples of failed reprojection coordinates (this output comes from my custom script that uses dirty-reprojectors as a dependency and is here only to reference other coords that convert to null):

Why is that? 🤔 Is it a bug, or is it "a feature"? Why doesn't the conversion work for Puerto Rico as well? Any help greatly appreaciated! 🙏

Never mind, after extensive googling I found the answer myself: d3/d3-geo#152. Hope this will be supported soon!

@BugsBunny338 Did you ever find a method of getting PR data to show through dirty-reprojectors?
