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).

Controls persistence of user-driven changes in axis attributes, if not overridden in the individual axes. Defaults to `layout.uirevision`.
