Choropleth Map - (React, D3 - HIV/AIDS data)","description":"This choropleth map visualizes the global share of the population infected with HIV/AIDS for the year 2017, using a yellow-to-red sequential color scale to encode prevalence rates. Countries with missing data appear in gray. The visualization is built with React and D3 v6, using `geoNaturalEarth1` and `geoPath` for map projection, `geoGraticule` for grid lines, and `topojson` to convert world atlas data into GeoJSON features. It renders as SVG, pulling HIV prevalence data from an IHME CSV dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa3207938aa94c6899a80ae5f5efa068?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
