Donut whose arcs sweep in on springs; hovering a segment or legend row expands it and swaps the rolling centre total for that segment's share.
Horizontal funnel whose centred bars grow in stage by stage, with conversion from the top and drop-off labelled between stages.
Ranking lines over time drawn as smooth S-curves; hovering or focusing a series highlights it, dims the rest and shows rank changes.
100% stacked bars or areas showing each series' share per period; toggling between them re-stacks with springs, with a period tooltip and a legend that hides series.
KPI cards with rolling numbers, an up/down delta badge and a sparkline that draws in, with a crosshair on hover or arrow keys.
