{"version":"1.0","type":"rich","title":"HIV/AIS Choropleth Map","description":"This choropleth map visualizes the share of the population infected with HIV/AIDS for the year 2017, using a sequential yellow-orange-red color scale to encode prevalence rates across countries. Gray marks indicate missing data. The visualization combines React state management with D3 utilities, including `d3.geoNaturalEarth1` for the map projection, `d3.geoPath` for rendering SVG paths, and `d3.scaleSequential` with `interpolateYlOrRd` for color encoding. Country boundaries and graticules are drawn from TopoJSON data, while prevalence values come from the IHME dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/41cc80d2391d4f7cb99c349334c4cd1b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
