It uses a Mercator projection via `geoMercator` and `geoPath` from d3, rendering country boundaries from World Atlas TopoJSON and graticules. React components manage state with `useDataViews` and `useDataMap`, while circles display tooltips showing country names on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ffe030d23ee444339a1a41b347c34c69?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
