This interactive choropleth map displays the global prevalence of HIV/AIDS in 2017, using a yellow-orange-red sequential color scale to encode the number of people living with the disease per country. Built with React and D3 v5, it projects country boundaries using `geoNaturalEarth1` and renders them via `geoPath`, with missing data shown in light blue. Data comes from the Missing Migrants Dataset and World Atlas TopoJSON, with country codes matched through a CSV lookup table.
