{"version":"1.0","type":"rich","title":"Immigrants flow map between countries","description":"This map visualizes immigrant flows between countries using curved lines on a geographic projection. The visualization uses D3’s geoNaturalEarth1 projection and geoPath to render country boundaries, graticules, and flow paths, with React managing the data loading. Immigration data from a 2020 CSV file is processed to extract origin and destination coordinates, and only valid country pairs are displayed. The map uses SVG for rendering, with flows colored in teal to distinguish them from the gray sphere and country fills.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b1a924673f174674b25ec7d26d7452a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
