          accesstoken
              Sets the mapbox access token to be used for this mapbox
              map. Alternatively, the mapbox access token can be set
              in the configuration options under `mapboxAccessToken`.
              Note that accessToken are only required when `style`
              (e.g with values : basic, streets, outdoors, light,
              dark, satellite, satellite-streets ) and/or a layout
              layer references the Mapbox server.
          bearing
              Sets the bearing angle of the map in degrees counter-
              clockwise from North (mapbox.bearing).
          bounds
              :class:`plotly.graph_objects.layout.mapbox.Bounds`
              instance or dict with compatible properties
          center
              :class:`plotly.graph_objects.layout.mapbox.Center`
              instance or dict with compatible properties
          domain
              :class:`plotly.graph_objects.layout.mapbox.Domain`
              instance or dict with compatible properties
          layers
              A tuple of
              :class:`plotly.graph_objects.layout.mapbox.Layer`
              instances or dicts with compatible properties
          layerdefaults
              When used in a template (as
              layout.template.layout.mapbox.layerdefaults), sets the
              default property values to use for elements of
              layout.mapbox.layers
          pitch
              Sets the pitch angle of the map (in degrees, where 0
              means perpendicular to the surface of the map)
              (mapbox.pitch).
          style
              Defines the map layers that are rendered by default
              below the trace layers defined in `data`, which are
              themselves by default rendered below the layers defined
              in `layout.mapbox.layers`.  These layers can be defined
              either explicitly as a Mapbox Style object which can
              contain multiple layer definitions that load data from
              any public or private Tile Map Service (TMS or XYZ) or
              Web Map Service (WMS) or implicitly by using one of the
              built-in style objects which use WMSes which do not
              require any access tokens, or by using a default Mapbox
              style or custom Mapbox style URL, both of which require
              a Mapbox access token  Note that Mapbox access token
              can be set in the `accesstoken` attribute or in the
              `mapboxAccessToken` config option.  Mapbox Style
              objects are of the form described in the Mapbox GL JS
              documentation available at
              https://docs.mapbox.com/mapbox-gl-js/style-spec  The
              built-in plotly.js styles objects are: carto-
              darkmatter, carto-positron, open-street-map, stamen-
              terrain, stamen-toner, stamen-watercolor, white-bg  The
              built-in Mapbox styles are: basic, streets, outdoors,
              light, dark, satellite, satellite-streets  Mapbox style
              URLs are of the form:
              mapbox://mapbox.mapbox-<name>-<version>
          uirevision
              Controls persistence of user-driven changes in the
              view: `center`, `zoom`, `bearing`, `pitch`. Defaults to
              `layout.uirevision`.
          zoom
              Sets the zoom level of the map (mapbox.zoom).
