{"version":"1.0","type":"rich","title":"HIV/AIDS Choropleth Map","description":"A choropleth map displays HIV/AIDS prevalence among adults aged 15–49 for the year 2017, with countries colored on a yellow-orange-brown sequential scale from `d3.scaleSequential` and `interpolateYlOrBr`, while nations lacking data appear gray. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries, graticules, and interiors from a TopoJSON world atlas. Data comes from a CSV of population infection rates, joined to countries via ISO numeric codes; React manages the component state and rendering as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4554cf5f9031405981baa1340f15b794?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
