Same data as the stacked area, but centered baseline. Reads as "shapes over time" rather than "totals over time" — easier to see individual category trajectories at the cost of a less legible total. Good for narrative slides, board updates, marketing visuals.
D3 v7 d3.stack with stackOffsetWiggle. Drop new data into SERIES.
const SERIES = [ { name: "Marketplace", values: [340,...] }, // ... etc ];
Composition trends where individual shapes are the story. Skip when totals matter — use stacked area. Avoid when you have <3 categories — a multi-line chart reads cleaner.
Wider band = larger AUM that quarter. Centered baseline removes the "starts-at-zero" anchor, which is why this works for narrative but not for precise totals.
