What c# model will serialize to a JSON object with dynamic property names each having a list of lists of values?

Question

What data structure/collection in C# that when I serialize using Newtonsoft.Json would give me a result like this, where the property names "data_point1" are dynamic and defined at runtime?

{
"data": {
    "data_point1": [
      [
        string,
        string
      ],
      [
        string,
        string
      ]
    ],
    "data_point2": [
        [
          string,
          string
        ],
        [
          string,
          string
        ]
      ],
   }
}

I tried with List of Dictionaries and it gave result like below:

{
    [
        {
            "data_point1": [
                [
                    string,
                    string
                ]
            ],
            "data_point2": [
                [
                    string,
                    string
                ]
            ]
        }
    ]
}

Edit1: changed "Property" to "data_point" as it was confusing. Dataset "data" has thousands of data points, each data point is a collection of data at a specific time.

Edit2: for anyone who this this not real Json, this is from an instruction of a 3rd party API I have to push data to

{ 
    "userToken": "XXXX-XXXX-XXXX-XXXX", 
    "sessionToken": "XXXX-XXXX-XXXX-XXXX", 
    "tvqs": 
        { 
          "tag1": [ [ "2018-01-09T12:00:00.0000000-05:00", "value" ] ], 
          "tag2": [ 
                    [ "2018-01-09T11:59:55.0000000-05:00", "value" ] , 
                    [ "2018-01-09T12:00:00.0000000-05:00", "value" ] 
                  ]  
        }
}

This can be done as a dictionary with two nested lists inside.

{
//Dictionary
"data": {
    // Dictionary Key with value List<List<string>>
    "Property1": [
      //Entry in List<List<string>>
      [
        //Entry in List<string>
        string,
        string
      ],
      [
        string,
        string
      ]
    ],
   }
}

using System.Collections.Generic;

var data = new Dictionary<string, List<List<string>>>();
