{"version":"1.0","type":"rich","title":"Map with Selectable Countries","description":"This example shows a choropleth map of world countries colored by economic grouping, with interactive selection: clicking a country dims all others and highlights the chosen region, and clicking again clears the selection. A color legend filters the map to a single category. The visualization uses D3 v5 with `geoNaturalEarth1` projection and `geoPath` for rendering SVG paths, plus `zoom` for panning. Data comes from TopoJSON and TSV files via the world-atlas package, with colors assigned by `scaleOrdinal`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f33f886e0cb14d4ab0aab8238a2198ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
