When to Use a Chord Diagram
Chord diagrams work best when flows go in multiple directions between the same set of categories, not in one clear sequence.
- Trade Flows Between Regions: Show import/export relationships between countries or regions, sized by trade volume.
- Customer Movement Between Tiers: Show how customers move between product tiers or subscription plans over time.
- Cross-Team Collaboration: Show which teams or departments work together most, useful in an org effectiveness review.
- Supply Chain Relationships: Show flows between suppliers, manufacturers, and distribution regions.
- Customer Migration Patterns: Show movement between vendors, brands, or competitor products.
- Referral or Network Analysis: Show which sources or partners refer business to which others.
