          color
              Sets the color for each cluster step.
          colorsrc
              Sets the source reference on Chart Studio Cloud for
              `color`.
          enabled
              Determines whether clustering is enabled or disabled.
          maxzoom
              Sets the maximum zoom level. At zoom levels equal to or
              greater than this, points will never be clustered.
          opacity
              Sets the marker opacity.
          opacitysrc
              Sets the source reference on Chart Studio Cloud for
              `opacity`.
          size
              Sets the size for each cluster step.
          sizesrc
              Sets the source reference on Chart Studio Cloud for
              `size`.
          step
              Sets how many points it takes to create a cluster or
              advance to the next cluster step. Use this in
              conjunction with arrays for `size` and / or `color`. If
              an integer, steps start at multiples of this number. If
              an array, each step extends from the given value until
              one less than the next value.
          stepsrc
              Sets the source reference on Chart Studio Cloud for
              `step`.
