What it is
Variable Radius Pie Chart (a.k.a. nightingale rose) keeps the angle = share rule but extends each slice’s radius by a second metric — so volume × magnitude reads at a glance.
What it does
Pie with each slice extended to a per-slice radius driven by a second metric, with tooltip and legend.
Why use it
Two metrics in one chart, in the form your audience already knows.
Three ways teams use it
Sales
Customer share by region (angle) × LTV (radius).
Marketing
Channel mix (angle) × conversion rate (radius).
Logistics
SKU share (angle) × margin (radius).
