{"version":"1.0","type":"rich","title":"V3 Immigrants flow map between countries","description":"This interactive map visualizes global immigrant flows between countries for 2020, based on UN migration data. Clicking a country highlights its origin by turning it red and draws curved flow lines to its destinations, with stroke color encoding the number of immigrants via a sequential blue-purple color scale. The visualization uses d3.geoNaturalEarth1 projection and d3.geoPath to render world map features, while React manages the selection state and d3.zoom enables pan and zoom interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5b270f8a44914e4080e60db88d7fb86d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
