If this toggle is enabled, a Zoom Out button will be
placed at the top left corner of the visual. By pressing this button, the bubble
chart will navigate one level higher in the drill down hierarchy.
If the current view is displaying the top level of the drill down hierarchy (or your bubble chart features only one level of hierarchy in the Categories field), the Zoom Out button will be hidden.

Sorry about that.
