{"version":"1.0","type":"rich","title":"Cloropleth","description":"This choropleth displays world countries colored by economic classification, with a color legend showing the ordinal scale’s domain. Built with D3 v5, it uses `d3.geoPath` and `geoNaturalEarth1` to project TopoJSON data from world-atlas, joined with ISO country codes from a TSV file. The map supports zooming via `d3.zoom`, and hovering highlights countries in red. A custom `colorLegend` component renders colored circles and text labels, while `schemeSpectral` provides the sequential color range.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/694a81e9ba384f679db3651ac150026f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
