Users can click on legend items to highlight or filter specific categories, with unselected groups fading to 20% opacity. The map uses d3.geoNaturalEarth1 projection and d3.geoPath for geographic rendering, while d3.zoom enables pan and zoom interactions. Data comes from the World Atlas TopoJSON dataset, combined with TSV metadata for country attributes. The visualization is built with D3 v5 and rendered as SVG elements, with hover effects that turn countries red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/470adde29ef748f7adea624a25989dc2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
