{"version":"1.0","type":"rich","title":"V4 Immigrants flow map between countries","description":"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.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/68860b33731244fc95636d54512890dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
