Human Migration Has Surged Since 2000: Maps Show Where People Are Going
Hacker News (AI keywords)3 days agoCommentaryNature’s headline indicates a data-driven look at how human migration has accelerated since 2000. The article appears to use maps to show where people are moving, but no body text was provided, so specific countries, causes, datasets, or policy implications cannot be confirmed. Based on the title alone, the piece is relevant to readers tracking demographic change, urbanization, labor mobility, climate pressure, and geopolitical shifts.
Spherical Voronoi Diagram
Hacker News (AI keywords)11 days agoTutorialJason Davies’ page demonstrates a spherical Voronoi diagram, where seed points divide the surface of a globe into nearest-neighbor regions. It relates the visualization to circumcircles and Delaunay triangulation. The implementation notes say it uses a randomized incremental algorithm to compute the 3D convex hull of spherical points, equivalent to their spherical Delaunay triangulation, and that the project remains a work in progress.
