{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15-49 in 2017, using a yellow-orange sequential color scale where darker shades represent higher infection rates. Countries with missing data appear in grey. Built with React and D3 v5, the visualization loads world country boundaries from a TopoJSON dataset and HIV prevalence data from a CSV file. The code projects geographic coordinates using `geoNaturalEarth1`, renders country shapes with `geoPath`, and overlays graticules via `geoGraticule`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2af859afe7284181933cee4715e6fb4a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
