Sigma Multi-Edge Trade Routes
Trade-route graph between 12 major world ports where every port pair can have multiple parallel edges (one per shipping line operating that route), rendered as curved edges so they don't visually overlap. Each edge is coloured by carrier (Maersk, MSC, CMA-CGM, Hapag-Lloyd, etc.)

When to use this template
This visualization excels at revealing the intensity and competition within pairwise relationships where multiple distinct entities operate between the same two nodes. It helps identify dominant connections, the specific actors driving them, and where competition or redundancy exists, which is crucial for understanding complex network dynamics and resource allocation.
- Network data with distinct source and target nodes.
- Multiple parallel edges possible between any node pair.
- Each edge having a categorical identifier (e.g., carrier name).
- Each edge having a quantitative value (e.g., volume, capacity).
- Node positions pre-calculated or arranged circularly.
- Relatively small to medium number of nodes (e.g., <100).
