{"version":"1.0","type":"rich","title":"Choropleth Map with interactions","description":"An interactive choropleth map encodes a country's economy category through a spectral color scale. Pan and zoom via D3's `zoom` and `event` APIs manipulate the SVG projection, while clicking a legend tick highlights only countries in that category. Hovering reveals the country name and value via a `title` element. The map uses `d3.geoPath` and `geoNaturalEarth1` on World Atlas TopoJSON, with the legend built from `scaleOrdinal` and `schemeSpectral`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f23af7ade513428db6bb620bc97d279b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
