{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes the world’s economies, coloring each country according to its economic classification using a spectral color scale. The map displays the geographic distribution of these categories, with hover states revealing a country’s name and category. Built with D3.js (v5), the visualization uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to render the map from world-atlas TopoJSON and TSV data. A custom `colorLegend` component, drawn as SVG circles and text, provides a reference for the color categories, while zooming is handled via D3’s `zoom` event and `event.transform`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b45294f25764762933bfa0e1d66bc84?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
