Users click legend swatches to filter the map, dimming non-matching countries and highlighting the selected category, which also reduces the sphere's opacity. The visualization uses d3.scaleOrdinal with a spectral scheme, loads data via d3.tsv and d3.json from the world-atlas package, and implements pan/zoom through d3.zoom.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/377c1dd9468b46dc92292de0c391e52e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
