{"version":"1.0","type":"rich","title":"HIV/AIDS Choropleth Map","description":"This choropleth map visualizes HIV/AIDS prevalence among adults aged 15–49 for the year 2019, using a sequential color scale with the interpolateGnBu scheme to represent varying levels of infection rates. The map projects country boundaries with d3.geoPath and a natural Earth projection, while filtering data to the selected year. Countries without matching data appear in a light gray fill. The visualization is built with React and D3 v7, pulling geographic features from the World Atlas TopoJSON and prevalence data from a CSV dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/df2f2e0888df4184af8e6cd0a7fc74ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
