Users can click legend swatches to filter highlighted countries, or click the map itself to explore regions. The visualization loads world topology and metadata from the world-atlas package, renders with SVG paths via d3.geoPath, and implements zooming through d3.zoom. A color legend module handles the clickable categorical filter, with hover states emphasizing individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89080808f9d549c48d39a7791ff2bc75?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
