{"version":"1.0","type":"rich","title":"HIV / AIDS Choropleth Map","description":"This visualization uses a natural Earth projection with D3’s `geoNaturalEarth1` and `geoPath` to draw world landmasses, graticules, and sphere outlines, overlaid with circles sized by city population via `scaleSqrt`. The React component loads World Atlas TopoJSON for boundaries and a CSV of HIV/AIDS prevalence data for cities, mapping each city’s longitude and latitude to screen coordinates. Semi-transparent teal circles highlight population distribution, while the underlying choropleth styling uses SVG paths and CSS classes. Data sources include the World Atlas TopoJSON and a Simplemaps-derived cities dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8542a88c863547eb8025d870d2afba54?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
