The Charles Darwin Map Projection

Benjamin Schmidt has created a map projection which has been optimized to show the track of the route of the Beagle during Charles Darwin's 1831-1836 famous survey voyage. Data-driven projections: Darwin's world is an Observable Notebook which visualizes the track of the Beagle on a map that preserves continuity near the areas where the Beagle sailed, at the expense of areas of the world that are distant from the path of Darwin's voyage.

Because the map is created in Observable you can change the data to create your own data driven map projections. If you click on the arrow next to the 'path' section of the notebook then you can edit and change the polyline co-ordinates for the Beagle's voyage to any polyline that you want. The notebook will then create a map projection based on your data.

The 'Data-driven projections: Darwin's world' notebook is a fork of the Voronoi Projection. This Observable Notebook creates a map projection based on the centroids of the 43 largest countries in the world.
