{"version":"1.0","type":"rich","title":"Map with Selectable Countries","description":"This interactive choropleth map visualizes world countries colored by economic classification, with a linked legend that filters the map based on selected categories. Clicking a country either selects or deselects it, dimming all other countries; clicking a legend category toggles the map to show only countries in that category. The map uses `d3.geoPath` with the `geoNaturalEarth1` projection, `d3.zoom` for pan and zoom, and `d3.scaleOrdinal` with the spectral scheme for coloring. Data comes from the world-atlas TSV and TopoJSON files, rendered as SVG paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a81255d9869427fb5b35f0f3c462f56?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
