I have a .json file that contains string to double array value. Currently I can get a “Map<String, List<List>>” which works but, I would like to get a “Map<String, List>” back instead.

  static String JSON = """
      {
        "data1": [ [ 1, 2, 3], [4, 5, 6] ],
        "data2": [ [ 9, 8, 7], [6, 5, 4] ]
      }
      """;

    public static void main(String[] args){
        ObjectMapper mapper = new ObjectMapper();
        Map<String, List<List<Double>>> values = mapper.readValue(JSON, Map.class);
    }

How could I set this up so that instead of a List<Double> I could have a List<MyPoint> instead.

This is similar to How to use Jackson to deserialise an array of objects but I need to include a conversion.
