Scroll or pinch to zoom. D3’s geographic projections allow features to be rotated about three axes. The three angles used are called Euler angles, and in D3 they specify the following sequence of rotations: This sequence is convenient, since if we approximate the globe as a sphere, the first two angles can be used to specify a central meridian λ0 and central meridian φ0 by simple negation: [-λ0, -φ0], and the third angle allows oblique projections. Interactive Rotations A naïve implementation simply takes the x- and y-coordinates in 2D screen space and uses them directly as the first two Euler angles mentioned above. However, the geographic start point of the gesture often moves at a different speed to the cursor, making it difficult to control. Naïve implementation (left) and improved version (right). An improved implementation ensures the geographic start point remains under the cursor where possible.
