Chord Diagram
Circular chord ribbons: every pairwise flow, perfectly weighted.
Chord Diagram is the chart for symmetric relationship matrices: co-purchase, origin↔destination, referral↔conversion. Categorical arcs sit around a ring, ribbons connect them with width = flow magnitude.
Directed (Source→Target) or undirected modes, sortable groups (alphabetical / by total / data order), per-group palette, ribbon color source (source/target/larger), hover highlighting, configurable tooltip + cross-filter.
Sankey is for left-to-right flow. Chord is for circular, symmetric flow, and looks elegant at a glance.
Three ways teams use it.
Co-purchase matrix, which categories sell together.
Origin ↔ destination passenger volume.
Cross-channel referral flow.
