{"version":"1.0","type":"rich","title":"HIV Choropleth","description":"This choropleth maps global migration events, with each point representing a single incident of death or disappearance. The map uses a square-root size scale to encode the total number of dead and missing, with semi-transparent teal circles overlaid on a world atlas. Rendered using React and SVG, the visualization employs `d3.geoNaturalEarth1` for the projection, `d3.geoPath` for landmasses and graticules, and `d3.scaleSqrt` for point sizing. Data comes from the Missing Migrants Dataset, while country boundaries are sourced from the World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/31b37a420e9948c7be78672facb12132?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
