The 'textfont' property is an instance of Textfont
that may be specified as:
  - An instance of :class:`plotly.graph_objs.histogram2dcontour.Textfont`
  - A dict of string/value properties that will be passed
    to the Textfont constructor

    Supported dict properties:

        color

        family
            HTML font family - the typeface that will be
            applied by the web browser. The web browser
            will only be able to apply a font if it is
            available on the system which it operates.
            Provide multiple font families, separated by
            commas, to indicate the preference in which to
            apply fonts if they aren't available on the
            system. The Chart Studio Cloud (at
            https://chart-studio.plotly.com or on-premise)
