Sets the level from which this trace hierarchy is rendered. Set `level` to `''` to start from the root node in the hierarchy. Must be an "id" if `ids` is filled in, otherwise plotly attempts to find a matching item in `labels`.

Sets the number of rendered sectors from any given `level`. Set `maxdepth` to *-1* to render all the levels in the hierarchy.

Sets the color of each sector of this trace. If not specified, the default trace color set is used to pick the sector colors.

Sets the color of the line enclosing each sector. Defaults to the `paper_bgcolor` value.

Determines whether or not the color domain is computed with respect to the input data (here colors) or the bounds set in `marker.cmin` and `marker.cmax`  Has an effect only if colorsis set to a numerical array. Defaults to `false` when `marker.cmin` and `marker.cmax` are set by the user.

Sets the lower bound of the color domain. Has an effect only if colorsis set to a numerical array. Value should have the same units as colors and if set, `marker.cmax` must be set as well.

Sets the upper bound of the color domain. Has an effect only if colorsis set to a numerical array. Value should have the same units as colors and if set, `marker.cmin` must be set as well.

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 colorsis set to a numerical array. Value should have the same units as colors. Has no effect when `marker.cauto` is `false`.

Sets the colorscale. Has an effect only if colorsis 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,Earth,Electric,Viridis,Cividis.
