Example:

>>> from snowflake.snowpark.functions import col, to_geography
>>> df = session.create_dataframe(['POINT(-122.35 37.55)', 'LINESTRING(-124.20 42.00, -120.01 41.99)'], schema=['g'])
>>> df = df.select(to_geography(col("g")).alias("geography"))
>>> df.select(st_asgeojson(col("geography"))).collect()
[Row(ST_ASGEOJSON("GEOGRAPHY")='{\n  "coordinates": [\n    -122.35,\n    37.55\n  ],\n  "type": "Point"\n}'), Row(ST_ASGEOJSON("GEOGRAPHY")='{\n  "coordinates": [\n    [\n      -124.2,\n      42\n    ],\n    [\n      -120.01,\n      41.99\n    ]\n  ],\n  "type": "LineString"\n}')]
