{"version":"1.0","type":"rich","title":"HIV Choropleth","description":"This choropleth map visualizes the global prevalence of HIV among adults aged 15–49 in 2017, with countries colored on a yellow-orange-red sequential scale based on infection rates. Built with React and D3 v5, it uses `geoNaturalEarth1` and `geoPath` to render world country boundaries, graticules, and interiors from TopoJSON data. Country codes are joined from an ISO-3166 CSV dataset to map each feature to its HIV prevalence value, while gray indicates missing data. The color scale uses `scaleSequential` with `interpolateYlOrRd`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8b62b2b8ffdd49b9af46755885c61a2a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
