          Charts
          Returns a list of Charts, ordered by creation date (newest first).  A Chart is chosen by Pollster editors. One example is \"Obama job approval - Democrats\". It is always based upon a single Question.  Users should strongly consider basing their analysis on Questions instead. Charts are derived data; Pollster editors publish them and change them as editorial priorities change. 
  
          This method makes a synchronous HTTP request by default. To make an
          asynchronous HTTP request, please define a `callback` function
          to be invoked when receiving the response.
          >>> def callback_function(response):
          >>>     pprint(response)
          >>>
          >>> thread = api.charts_get(callback=callback_function)
  
          :param callback function: The callback function
              for asynchronous request. (optional)
          :param str cursor: Special string to index into the Array
          :param str tags: Comma-separated list of tag slugs. Only Charts with one or more of these tags and Charts based on Questions with one or more of these tags will be returned.
          :param date election_date: Date of an election, in YYYY-MM-DD format. Only Charts based on Questions pertaining to an election on this date will be returned.
          :return: InlineResponse200
                   If the method is called asynchronously,
                   returns the request thread.
