Where did this transfer actually originate, and where does it go? Pick a chain root from the dropdown — the Sankey renders that chain's source-to-target ribbons, and the hop-by-hop table beside it lists every edge ordered by depth. Single-leg transfers (sales, raw external arrivals) appear as chain members but don't contribute Sankey ribbons.
Source account → target account ribbons for the selected chain. Ribbon thickness = SUM(hop_amount). Single-leg transfers don't render here — see the detail table for every chain member.
Every edge in the selected chain, ordered root → leaf by depth.
