Use the dials on the left to adjust the rotation of a geographic projection. D3 supports three-axis rotation, allowing you to adjust the lambda (λ), phi (φ) and gamma (γ) axes.

This map uses an orthographic projection with D3.js and Topojson to draw a map of the world’s countries onto a globe, rendered here with a graticule that is 10° by 10°.

The world countries polygons were downloaded from ArcGIS.
