This choropleth map visualizes the share of the population infected with HIV/AIDS for the year 2017, using a yellow-orange-red sequential color scale to show prevalence across countries. The visualization renders a natural Earth projection with graticules and country boundaries via `d3.geoNaturalEarth1` and `d3.geoPath`, with missing data marked in gray. Built with React and D3 v5, it joins country codes from the ISO-3166 dataset to HIV prevalence data from the IHME, displaying the result as an SVG.
