          **Key Arguments:**
              - ``filepath`` -- path to the file to write the json content to. Default *None*
  
          **Return:**
              - ``renderedData`` -- the data rendered as json
  
          **Usage:**
  
              To render the data set as json:
  
              .. code-block:: python
  
                  print dataSet.json()
  
              .. code-block:: json

                      {
                          "address": "belfast, uk",

                          "pet": "dog"
                      },

                      }
                  ]
  
              and to save the json rendering to file:
  
              .. code-block:: python
  
                  dataSet.json("/path/to/myfile.json")
