{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries by their economy category using a categorical color scale. The map is rendered as SVG with geographic paths projected via `d3.geoNaturalEarth1` and encoded with `d3.geoPath`, while panning and zooming are handled by `d3.zoom`. A legend, built with custom code, displays color-coded circles in `d3.scaleOrdinal`’s `schemeSpectral` range. Data comes from World Atlas TopoJSON and TSV files, loaded with `d3.json` and `d3.tsv`, and each country shows its name and value on hover via a `<title>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea2eb5172d9b4683bf88e18a671fa67a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
