This choropleth map visualizes the global share of the population infected with HIV/AIDS in 2017, sourced from IHME data. The map uses a sequential yellow-orange-red color scale to encode prevalence rates across countries, with gray representing missing data. Built with React and D3 v5, it renders a Natural Earth projection using `geoNaturalEarth1` and `geoPath`, with country boundaries from the world-atlas TopoJSON. The data is loaded via D3’s `csv` and joined to map features using ISO alpha-3 codes.
