Fork of HIV/AIDS Choropleth Map
This choropleth map visualizes the global share of the population infected with HIV/AIDS among adults aged 15–49 in 2017, using a yellow-to-red sequential color scale. Country boundaries come from the World Atlas TopoJSON, while prevalence data is loaded from a CSV and joined to countries via ISO numeric codes. The visualization is built with React and D3 v5, using `geoNaturalEarth1` and `geoPath` for projection, `geoGraticule` for overlaying grid lines, and `scaleSequential` with `interpolateYlOrRd` to encode values. Countries without data appear gray.
