      ----------
      serializer : Union[HtmlSerializer[T], WidgetSerializer[T]]
          serializer to prepare an output
      file : filename or file-like object
          The file to write the HTML output to. If None writes to output.html
      requirejs: bool , default: True
          whether to include requirejs library into output HTML or not
      connected: bool , default False
          indicates whether internet connection is available or not,
          if 'True' then CDN urls will be used to load javascript otherwise
          javascript libraries will be injected directly into HTML output.
          Set to 'False' to make results viewing possible when the internet
          connection is not available.
