              instance or dict with compatible properties
          bargap
              Sets the gap between bars of adjacent location
              coordinates. Values are unitless, they represent
              fractions of the minimum difference in bar positions in
              the data.
          barmode
              Determines how bars at the same location coordinate are
              displayed on the graph. With "stack", the bars are
              stacked on top of one another With "overlay", the bars
              are plotted over one another, you might need to reduce
              "opacity" to see multiple bars.
          bgcolor
              Set the background color of the subplot
          domain

              instance or dict with compatible properties
          gridshape
              Determines if the radial axis grid lines and angular
              axis line are drawn as "circular" sectors or as
              "linear" (polygon) sectors. Has an effect only when the
              angular axis has `type` "category". Note that
              `radialaxis.angle` is snapped to the angle of the
              closest vertex when `gridshape` is "circular" (so that
              radial axis scale is the same as the data scale).
          hole
              Sets the fraction of the radius to cut out of the polar
              subplot.
          radialaxis
              :class:`plotly.graph_objects.layout.polar.RadialAxis`
              instance or dict with compatible properties
          sector
              Sets angular span of this polar subplot with two angles
              (in degrees). Sector are assumed to be spanned in the
              counterclockwise direction with 0 corresponding to
              rightmost limit of the polar subplot.
          uirevision
              Controls persistence of user-driven changes in axis
              attributes, if not overridden in the individual axes.
              Defaults to `layout.uirevision`.
