LabelingFunction -> f labels every wedge with f[value]. Wrapping the result in Placed[label, position] decides where along the wedge's radius the label sits: "RadialCenter" (the default) centres it, "RadialInner" and "RadialOuter" push it towards the hub or the rim, and "RadialCallout" puts it outside the pie on a leader line.
