Leaflet Shipping Routes Map
A many-to-many transport-network map: every leg between two ports (or rail nodes, or fiber landings) is drawn as a colored polyline whose width and color encode an attribute — annual TEU volume, average transit time, or revenue. Distinct from the route map (#44), which is one pol

When to use this template
This visualization makes obvious the structure, capacity, and performance of complex, many-to-many transportation or communication networks. Analysts reach for it to identify high-volume corridors, critical links, or potential bottlenecks within a system where multiple paths can exist between any two points. It helps understand the overall flow and capacity dynamics across an entire network rather than focusing on a single sequential journey.
- Network data with distinct origin and destination nodes.
- Edges (connections) requiring geographic coordinates for both endpoints.
- Quantitative metrics associated with each edge (e.g., volume, time, cost).
- Datasets where nodes can have aggregated metrics (e.g., total throughput).
- Visualizing systems with multiple, potentially parallel, connections between nodes.
- Data representing a whole system's flow, not a single route.
