{"version":"1.0","type":"rich","title":"d3 Choropleth Map","description":"This interactive choropleth map visualizes countries colored by economic classification, using a spectral color scale with a legend for reference. The map responds to zoom and hover interactions, highlighting countries on hover. Built with d3.js, it uses `geoPath` and `geoNaturalEarth1` for geographic projection, `scaleOrdinal` and `schemeSpectral` for coloring, and a custom `colorLegend` component. Data is loaded from world-atlas TSV and TopoJSON sources, rendered as SVG paths on a blue sphere background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f76a5796f6a462da25af706df235538?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
