It presents a choropleth world map colored by selected metrics, a leaderboard for ranking countries, a detail view for individual country comparisons, and a correlation matrix between factors. Users can switch views, filter by year or region, and adjust rank ranges. Built with D3 v7, it uses `d3.geoPath` with Natural Earth projections for the map, `d3.scaleSequential` for color encoding, and animated transitions for temporal changes, rendering in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c9f7c7a4312419eb0e3e406d8fac423?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
