{"version":"1.0","type":"rich","title":"Chloropeth Map","description":"A choropleth map colors countries by economy using a D3 v5 ordinal color scale with a spectral scheme. The visualization uses the `d3.geoPath` and `d3.geoNaturalEarth1` projection to render geographic boundaries from TopoJSON world-atlas data, with a legend built via a custom `colorLegend` function. Hovering highlights a country in pink, and a zoom interaction is implemented with `d3.zoom`. The map is rendered as SVG with a dark blue ocean background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e02e24dbfa714a658349c511b92a21fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
