          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 the marker color. 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.funnel.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: Blackbody,Bluered,Blues,Cividis,Earth,E
              lectric,Greens,Greys,Hot,Jet,Picnic,Portland,Rainbow,Rd
              Bu,Reds,Viridis,YlGnBu,YlOrRd.
          colorsrc
              Sets the source reference on Chart Studio Cloud for
              `color`.
          line
              :class:`plotly.graph_objects.funnel.marker.Line`
              instance or dict with compatible properties
          opacity
              Sets the opacity of the bars.
          opacitysrc
              Sets the source reference on Chart Studio Cloud for
              `opacity`.
          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.
