{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economy classification, with a color legend and tooltips showing each country’s name and category. The visualization uses a natural Earth projection rendered as SVG paths via d3.geoPath, while TopoJSON and TSV data from the world-atlas package are loaded asynchronously. Users can pan and zoom the map using d3.zoom, and hovering highlights individual countries in red. The color scale uses d3.scaleOrdinal with a spectral scheme, and an interactive legend is built from custom d3 selections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a31bede0ab7543f2b267e998bf45c153?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
