{"version":"1.0","type":"rich","title":"HIV/AIDS Choropleth","description":"This chart visualizes global HIV/AIDS prevalence among adults aged 15-49 for the year 2017, using a sequential color scale from yellow to red to indicate severity, with countries lacking data highlighted in red. Built with React and D3 v5, it renders an SVG map using a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, overlaying graticules and country borders from TopoJSON data. The prevalence values are loaded from a CSV file and mapped to each country by name, with a sequential scale (`d3.scaleSequential` and `interpolateYlOrRed`) determining fill colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c727ca77d1eb44deb074df0f29b73600?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
