Module partition 

Hierarchical partition charts: geom_sunburst (under coord_polar) and geom_icicle (Cartesian). One band per hierarchy level; each node’s span is proportional to its value and nested inside its parent’s. Layout by StatPartition.

GeomPartition

Partition chart over the levels columns (outermost first), sized by weight (1 per row when unmapped). Drawn as sectors under a polar coord (sunburst) and as rectangles otherwise (icicle).
