This visualization presents a choropleth world map depicting HIV/AIDS prevalence rates for the year 2017. Country boundaries are rendered using the `geoNaturalEarth1` projection and `geoPath` from D3, with graticules and interiors drawn for context. The map is color-coded using a sequential yellow-orange-red scale (`scaleSequential(interpolateYlOrRd)`) applied to AIDS prevalence data, with missing data displayed in gray. The geographic data originates from World Atlas TopoJSON, while the prevalence statistics are sourced from a CSV dataset.
