{"version":"1.0","type":"rich","title":"HIV/AIDS choropleth map","description":"This choropleth map visualizes the global share of the population aged 15–49 infected with HIV/AIDS in 2017, using a yellow-orange-red sequential color scale. It renders country polygons via `d3.geoEqualEarth` and `d3.geoPath`, with graticules and interior boundaries drawn from TopoJSON world atlas data. Data comes from the IHME HIV/AIDS prevalence dataset, joined to country codes via the ISO-3166 slim CSV. React components manage state and loading, while D3 v5 handles projection, geospatial path generation, and color scaling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/71f8cc727311440381fc601c8fcc21be?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
