Users can click countries to highlight them, which dims all others and fades the background sphere. Clicking again deselects. A legend allows filtering by economic group. The visualization uses d3.geoNaturalEarth1 projection, d3.geoPath for rendering, and d3.zoom for pan/zoom. Data comes from the world-atlas TopoJSON and TSV files, with color mapping via d3.scaleOrdinal and d3.schemeSpectral.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b6de507a869d4e0581fd8a652b786a7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
