{"version":"1.0","type":"rich","title":"Choropleth map","description":"This choropleth map displays world economies by color, with a legend that filters countries by clicking a color category, dimming non-matching regions. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, while the legend is built with D3 scales and `d3.schemeSpectral`. Country data comes from the World Atlas TopoJSON and TSV files, rendered as SVG paths with zoom support via `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e713a1f995f2486a90aac5301f408cb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
