{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economic classification using a categorical ordinal color scale from `d3.scaleOrdinal` with the `schemeSpectral` palette. It renders world geography with `d3.geoPath` and a Natural Earth projection, loading TopoJSON country boundaries and TSV metadata from the world-atlas package. A custom color legend built with D3 selections appears alongside the map, while `d3.zoom` enables panning and zooming. The visualization uses SVG elements and includes hover effects that highlight individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/183fddd6b50347d9ae490fac5e4f7b60?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
