{"version":"1.0","type":"rich","title":"Map with selectable country","description":"This example presents a world map with countries colored by economic category, where clicking a country highlights it and dims all others; clicking again deselects it. The visualization includes a color legend with clickable swatches that filter the map’s opacity. Built with D3 v5, it uses `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.zoom` for the interactive map, rendered as SVG. Country data comes from World Atlas TopoJSON, while economic classifications load from a TSV file. A sequential ordinal color scale based on `schemeSpectral` drives the fill colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e8fb7116ed74aa09bb7e8c78ca199b1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
