<p>
Each node has a Position Panel whose <a>Panel.itemArray</a> is data bound to the "slices" property of the node data.
That "slices" property is an Array of data objects; for each item the <a>Panel.itemTemplate</a> produces a Shape whose
<a>Shape.geometry</a> is computed using a conversion function to generate a pie-shaped slice given a start angle
and a sweep angle from the item data.
Note that <a>Shape.isGeometryPositioned</a> is true to make sure all of the Shapes are positioned
by their computed geometries, independent of any stroke width.
Each slice Panel also has a tooltip showing some information.
