Users can click legend items to filter countries by income level, with non-selected countries dimmed to 10% opacity and a zoom interaction provided via d3.zoom. The map draws country boundaries from TopoJSON data augmented with TSV attributes, while the color legend uses d3.scaleOrdinal with an RdYlGn scheme for categorical coloring.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22b8480653a64429ab06db7a0d4516ab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
