This interactive choropleth map visualizes the global share of the population infected with HIV/AIDS in 2017, using data from OurWorldInData. Countries are colored on a yellow-to-red sequential scale based on prevalence, with gray indicating missing data. The visualization is built with React, rendering SVG shapes through d3.geoPath and a geoNaturalEarth1 projection, while d3-geo graticules and topojson mesh outlines delineate geographic boundaries. Country codes from the ISO-3166 dataset link the CSV data to world-atlas map features.
