          autocolorscale
              Determines whether the colorscale is a default palette
              (`autocolorscale: true`) or the palette determined by
              `marker.colorscale`. Has an effect only if in
              `marker.color`is set to a numerical array. In case
              `colorscale` is unspecified or `autocolorscale` is
              true, the default  palette will be chosen according to
              whether numbers in the `color` array are all positive,
              all negative or mixed.
          cauto
              Determines whether or not the color domain is computed
              with respect to the input data (here in `marker.color`)
              or the bounds set in `marker.cmin` and `marker.cmax`
              Has an effect only if in `marker.color`is set to a
              numerical array. Defaults to `false` when `marker.cmin`
              and `marker.cmax` are set by the user.
          cmax
              Sets the upper bound of the color domain. Has an effect
              only if in `marker.color`is set to a numerical array.
              Value should have the same units as in `marker.color`
              and if set, `marker.cmin` must be set as well.
          cmid
              Sets the mid-point of the color domain by scaling
              `marker.cmin` and/or `marker.cmax` to be equidistant to
              this point. Has an effect only if in `marker.color`is
              set to a numerical array. Value should have the same
              units as in `marker.color`. Has no effect when
              `marker.cauto` is `false`.
          cmin
              Sets the lower bound of the color domain. Has an effect
              only if in `marker.color`is set to a numerical array.
              Value should have the same units as in `marker.color`
              and if set, `marker.cmax` must be set as well.
          color
              Sets themarkercolor. It accepts either a specific color
              or an array of numbers that are mapped to the
              colorscale relative to the max and min values of the
              array or relative to `marker.cmin` and `marker.cmax` if
              set.
          coloraxis
              Sets a reference to a shared color axis. References to
              these shared color axes are "coloraxis", "coloraxis2",
              "coloraxis3", etc. Settings for these shared color axes
              are set in the layout, under `layout.coloraxis`,
              `layout.coloraxis2`, etc. Note that multiple color
              scales can be linked to the same color axis.
          colorbar
              :class:`plotly.graph_objects.scatter3d.marker.ColorBar`
              instance or dict with compatible properties
          colorscale
              Sets the colorscale. Has an effect only if in
              `marker.color`is set to a numerical array. The
              colorscale must be an array containing arrays mapping a
              normalized value to an rgb, rgba, hex, hsl, hsv, or
              named color string. At minimum, a mapping for the
              lowest (0) and highest (1) values are required. For
              example, `[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]`.
              To control the bounds of the colorscale in color space,
              use`marker.cmin` and `marker.cmax`. Alternatively,
              `colorscale` may be a palette name string of the
              following list: Greys,YlGnBu,Greens,YlOrRd,Bluered,RdBu
              ,Reds,Blues,Picnic,Rainbow,Portland,Jet,Hot,Blackbody,E
              arth,Electric,Viridis,Cividis.
          colorsrc
              Sets the source reference on Chart Studio Cloud for
              color .
          line
              :class:`plotly.graph_objects.scatter3d.marker.Line`
              instance or dict with compatible properties
          opacity
              Sets the marker opacity. Note that the marker opacity
              for scatter3d traces must be a scalar value for
              performance reasons. To set a blending opacity value
              (i.e. which is not transparent), set "marker.color" to
              an rgba color and use its alpha channel.
          reversescale
              Reverses the color mapping if true. Has an effect only
              if in `marker.color`is set to a numerical array. If
              true, `marker.cmin` will correspond to the last color
              in the array and `marker.cmax` will correspond to the
              first color.
          showscale
              Determines whether or not a colorbar is displayed for
              this trace. Has an effect only if in `marker.color`is
              set to a numerical array.
          size
              Sets the marker size (in px).
          sizemin
              Has an effect only if `marker.size` is set to a
              numerical array. Sets the minimum size (in px) of the
              rendered marker points.
          sizemode
              Has an effect only if `marker.size` is set to a
              numerical array. Sets the rule for which the data in
              `size` is converted to pixels.
          sizeref
              Has an effect only if `marker.size` is set to a
              numerical array. Sets the scale factor used to
              determine the rendered size of marker points. Use with
              `sizemin` and `sizemode`.
          sizesrc
              Sets the source reference on Chart Studio Cloud for
              size .
          symbol
              Sets the marker symbol type.
          symbolsrc
              Sets the source reference on Chart Studio Cloud for
              symbol .
