{"version":"1.0","type":"rich","title":"Fork of Fork of React & D3 Vibecoding Starter","description":"This choropleth map colors world countries by population, using darker blues for more populous nations while unlisted countries appear gray. A legend explains the visual encoding. The example loads world-atlas TopoJSON, converts it to GeoJSON features using topojson-client, and projects the map with d3.geoNaturalEarth1 and d3.geoPath. A d3.scaleLinear maps population values to a light-to-dark color range, and SVG paths render each country with tooltips showing population figures.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e9aa0a510be0469dbe2370f6ba393b56?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
