Deck.gl Global Great Circles
Global routes drawn as true great-circle paths — the shortest distance between two points on a sphere — rather than straight lines on a flat projection. Deck.gl's GreatCircleLayer computes the curved path on the GPU using spherical geometry and renders it with anti-aliased per-ar

When to use this template
This visualization accurately depicts the shortest paths between global locations, revealing true intercontinental connections and flows. It clarifies why seemingly indirect routes are actually the most efficient on a spherical Earth, making geographical relationships intuitive. Analysts use it to understand global movement patterns where spherical geometry is critical for correct interpretation.
- Datasets with origin and destination geographic coordinates.
- Global point-to-point connections or movement data.
- Large cardinality of distinct intercontinental routes.
- Data where path curvature on a sphere is analytically significant.
- Categorical or quantitative attributes for each individual path.
- Time-series data tracking evolving global flow patterns.
