              Determines if the layer will be inserted before the
              layer with the specified ID. If omitted or set to '',
              the layer will be inserted above every existing layer.
          circle
              :class:`plotly.graph_objects.layout.mapbox.layer.Circle
              ` instance or dict with compatible properties
          color
              Sets the primary layer color. If `type` is "circle",
              color corresponds to the circle color
              (mapbox.layer.paint.circle-color) If `type` is "line",
              color corresponds to the line color
              (mapbox.layer.paint.line-color) If `type` is "fill",
              color corresponds to the fill color
              (mapbox.layer.paint.fill-color) If `type` is "symbol",
              color corresponds to the icon color
              (mapbox.layer.paint.icon-color)
          coordinates
              Sets the coordinates array contains [longitude,
              latitude] pairs for the image corners listed in
              clockwise order: top left, top right, bottom right,
              bottom left. Only has an effect for "image"
              `sourcetype`.
          fill
              :class:`plotly.graph_objects.layout.mapbox.layer.Fill`
              instance or dict with compatible properties
          line
              :class:`plotly.graph_objects.layout.mapbox.layer.Line`
              instance or dict with compatible properties
          maxzoom
              Sets the maximum zoom level (mapbox.layer.maxzoom). At
              zoom levels equal to or greater than the maxzoom, the
              layer will be hidden.
          minzoom
              Sets the minimum zoom level (mapbox.layer.minzoom). At
              zoom levels less than the minzoom, the layer will be
              hidden.
          name
              When used in a template, named items are created in the
              output figure in addition to any items the figure
              already has in this array. You can modify these items
              in the output figure by making your own item with
              `templateitemname` matching this `name` alongside your
              modifications (including `visible: false` or `enabled:
              false` to hide it). Has no effect outside of a
              template.
          opacity
              Sets the opacity of the layer. If `type` is "circle",
              opacity corresponds to the circle opacity
              (mapbox.layer.paint.circle-opacity) If `type` is
              "line", opacity corresponds to the line opacity
              (mapbox.layer.paint.line-opacity) If `type` is "fill",
              opacity corresponds to the fill opacity
              (mapbox.layer.paint.fill-opacity) If `type` is
              "symbol", opacity corresponds to the icon/text opacity
              (mapbox.layer.paint.text-opacity)
          source
              Sets the source data for this layer
              (mapbox.layer.source). When `sourcetype` is set to
              "geojson", `source` can be a URL to a GeoJSON or a
              GeoJSON object. When `sourcetype` is set to "vector" or
              "raster", `source` can be a URL or an array of tile
              URLs. When `sourcetype` is set to "image", `source` can
              be a URL to an image.
          sourceattribution
              Sets the attribution for this source.
          sourcelayer
              Specifies the layer to use from a vector tile source
              (mapbox.layer.source-layer). Required for "vector"
              source type that supports multiple layers.
          sourcetype
              Sets the source type for this layer, that is the type
              of the layer data.
          symbol
              :class:`plotly.graph_objects.layout.mapbox.layer.Symbol
              ` instance or dict with compatible properties
          templateitemname
              Used to refer to a named item in this array in the
              template. Named items from the template will be created
              even without a matching item in the input figure, but
              you can modify one by making an item with
              `templateitemname` matching its `name`, alongside your
              modifications (including `visible: false` or `enabled:
              false` to hide it). If there is no template or no
              matching item, this item will be hidden unless you
              explicitly show it with `visible: true`.
          type
              Sets the layer type, that is the how the layer data set
              in `source` will be rendered With `sourcetype` set to
              "geojson", the following values are allowed: "circle",
              "line", "fill" and "symbol". but note that "line" and
              "fill" are not compatible with Point GeoJSON
              geometries. With `sourcetype` set to "vector", the
              following values are allowed:  "circle", "line", "fill"
              and "symbol". With `sourcetype` set to "raster" or
              `*image*`, only the "raster" value is allowed.
