This is an implementation in D3 of the adaptive composite map projections by Bernhard Jenny. We extended the method in the paper in two key ways: (1) We interpolate paths and handle edge cases more robustly than the paper's proof-of-concept implementation, and (2) We implemented smooth animations between map locations which provide global context for the move. Read our final paper here.
Usage:
Local map: Click and drag the cursor to move. Use schollwheel to zoom in/out.
Global map: Click and drag the cursor to draw a great-circle arc. Then click the Animate button to animate along the arc.
