{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This choropleth map colors world countries by economic classification using a spectral color scale, with hover effects and a legend showing the ordinal categories. The map supports zooming and panning via the `d3.zoom` API, while the sphere and country paths are rendered with `d3.geoPath` and the Natural Earth projection. Data is loaded from the `world-atlas` TopoJSON and TSV files, processed with the `topojson` feature function and `d3.tsv`, and assigned colors through `d3.scaleOrdinal` with `d3.schemeSpectral`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1427a9da631b44489060cb16b02589c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
