This visualization displays the global prevalence of HIV/AIDS among adults aged 15-49 for the year 2017, using a sequential color scale from yellow to red shaded across country boundaries. The React app loads world map topology from World Atlas TopoJSON and health data from a CSV source, then projects the map with d3.geoNaturalEarth1 and renders it as SVG paths. Countries missing data appear gray, while graticules and interior borders provide geographic context.
