{"version":"1.0","type":"rich","title":"D3 course - Missing Migrant Data","description":"This interactive visualization maps recorded migrant deaths and disappearances worldwide, with each city’s circle radius scaled by the square root of its reported total dead and missing. The map renders landmasses in gray on a dark globe, with graticules and country boundaries drawn via `d3.geoPath` and `d3.geoGraticule`. It projects the data using `d3.geoNaturalEarth1`, overlays circles via React SVG, and loads city records from a CSV, with sizes determined by `d3.scaleSqrt`. Missing migrant data comes from a public subset, while country shapes use the World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/347edb28fc60455f985aea151c31a88b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
