tiling.packing controls the layout algorithm:

• "squarify" (default) — tries to make rectangles close to square
• "binary" — binary subdivision
• "dice" — horizontal slices only
• "slice" — vertical slices only

textinfo controls what text appears inside rectangles: "label", "value", "percent parent", "percent root" — combine with "+".
