Dual Donut
Two donuts side-by-side: current vs prior, plan vs actual, the comparison view.
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.
Two donut charts in a row sharing a legend, with per-slice tooltips, total center labels, and cross-filtering.
A single donut shows composition; two donuts show how composition shifted, and that’s usually the story.
Three ways teams use it.
Revenue mix this year vs last.
Channel mix planned vs actual.
Headcount mix before vs after reorg.
