{"version":"1.0","type":"rich","title":"HIV/AIDS Making a Choropleth Map","description":"This example visualizes the share of the population infected with HIV/AIDS for countries worldwide in 2017, using a choropleth map rendered with SVG paths. Countries lacking data appear gray, while others are colored using a sequential yellow-orange-red color scale via `d3.scaleSequential` and `interpolateYlOrRd`. The map is built with React, D3’s `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` for graticules, alongside country boundaries from the world-atlas TopoJSON. Data comes from an IHME CSV joined to numeric country codes via ISO-3166 codes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/87dd19a12e684ab5bd366935d6bfe3da?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
