Countries are filled with a yellow-orange-red sequential color scale from `d3.scaleSequential` and `interpolateYlOrRd`, with gray for missing data. The map uses `d3.geoNaturalEarth1` projection and `d3.geoPath` on TopoJSON data from the World Atlas, rendering country boundaries and graticules via SVG. HIV prevalence data comes from IHME, joined to country codes via ISO-3166 reference data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e8330bc11044431a2559b82f06c757c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
