{"version":"1.0","type":"rich","title":"Map with Selectable Countries","description":"This interactive choropleth map displays world countries colored by their economic classification, with grayed-out, semi-transparent countries when one is selected. Clicking a country highlights it and shows its name and value in a tooltip; clicking again deselects it, and clicking a color legend swatch filters the map to that category. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering SVG paths, and `topojson.feature` to convert TopoJSON from the world-atlas package, joined with TSV metadata containing ISO codes and economy data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7fae1434d5374c7a916ac6a371593f8a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
