Pie charts labels
This variation of a donut chart demonstrates how to label each slice with text and leader lines that extend outward. A button click triggers a transition to new random data, with all elements—arcs, labels, and polylines—smoothly animating to their new positions. The visualization uses D3.js v3, employing `d3.layout.pie` for the pie layout, `d3.svg.arc` for the donut and outer arcs, and `transition.attrTween` with `d3.interpolate` to morph values. Text labels are positioned via `outerArc.centroid` and aligned left or right based on the slice’s mid-angle.
