This map visualizes immigrant flows between countries in 2020 using an interactive world map. Users can click a country to highlight it as the origin and display bundled curved paths projecting to all destination nations, with stroke opacity indicating connection strength. The visualization uses D3 v5's `geoNaturalEarth1` and `geoPath` for map rendering, `d3.ForceEdgeBundling` for curve grouping, and a `scaleSequential` color scale based on migration numbers. Country boundaries derive from TopoJSON world-atlas data, while migration statistics come from a CSV gist.
