Country boundaries are rendered with `d3.geoPath` using Natural Earth projection, while circle symbols sized by `d3.scaleSqrt` represent the selected metric at each country’s centroid. Data is loaded from a CSV file and merged with TopoJSON world geometry, with color and size legends providing context. Interactive zooming is enabled through `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d0ef2bfd6a314232ba207bd1b417cbc1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
