{"version":"1.0","type":"rich","title":"Map with Selectable Countries","description":"This map visualizes world countries colored by economic classification using a categorical color scale. Clicking a country highlights it while dimming all others, and clicking again deselects it. The map uses d3.geoNaturalEarth1 projection with d3.geoPath to render SVG paths from TopoJSON world-atlas data, while d3.zoom enables panning and zooming. A color legend with clickable swatches filters the map, and the visualization updates reactively through D3 data joins.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/841d0a338ece43aba80aff39cede6213?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
