{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors world countries by economic grouping, using a spectral color scale and an accompanying legend. Built with D3 v5 and TopoJSON, it loads country boundaries and metadata from the world-atlas package. The map renders as SVG paths via `d3.geoPath` with a natural Earth projection, supports zooming through `d3.zoom`, and highlights countries on hover. The color legend is a custom component using `d3.scaleOrdinal` and `d3.schemeSpectral`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d6be2b5e5c94467bbc5102218c61ea87?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
