The recommended way to install is viapoetry:poetry add marshmallow_geojsonUsing pip to install is also possible.pip install marshmallow_geojsonGEOJSONGeoJSONis a format for encoding a variety of geographic data structures.{
  "type": "Feature",
  "geometry": {
    "type": "Point",

  },
  "properties": {

  }
}GeoJSON supports the following geometry types: Point, LineString, Polygon,
MultiPoint, MultiLineString, and MultiPolygon. Geometric objects with
additional properties are Feature objects. Sets of features are contained by
FeatureCollection objects.Examples of usingCustom properties:from marshmallow.fields import Str, Nested
