What it is
Dual Donut renders two same-scale donut charts in parallel, perfect for any "before vs after" split — current vs prior, plan vs actual, treatment vs control. Per-slice tooltips and a unified legend keep it readable.
What it does
Two donut charts in a row sharing a legend, with per-slice tooltips, total center labels, and cross-filtering.
Why use it
A single donut shows composition; two donuts show how composition shifted — and that’s usually the story.
Three ways teams use it

Marketing
Channel mix planned vs actual.
