Variable-Radius Nested Donut
Variable-radius nested donut: two metrics per slice, one chart.

Variable-Radius Nested Donut combines angular share with radial magnitude: angle = share, radius = a second metric. Nest two of them and you have a four-metric composition chart in a single ring.
Donut with per-slice angle for share and per-slice radius for a second metric, nested for two breakdowns.
When a regular donut loses a metric: variable-radius keeps it.
Three ways teams use it.
Channel share (angle) and ROAS (radius).
Segment share and growth.
Plan share and ARPU.
