{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This choropleth map colors countries by economic classification using a natural Earth projection with an ordinal spectral color scale. The visualization supports zooming and panning through d3.zoom, with country names and income groups revealed on hover via SVG title elements. A custom color legend with circles and text labels is built using D3 data joins, while geographic data comes from the world-atlas TopoJSON dataset processed with topojson.feature and loaded via d3.tsv and d3.json. The map is rendered entirely in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c51ad8cda4242f1b0a391081a825e90?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
