{"version":"1.0","type":"rich","title":"Fork of React & D3 Vibecoding Starter","description":"This choropleth world map visualizes population data for nine countries, using darker blue shades to represent higher populations. It loads country boundaries from the world-atlas TopoJSON dataset, converts them to GeoJSON with topojson-client’s feature function, and renders them as SVG paths via d3.geoPath with a Natural Earth projection. A d3.scaleLinear color scale maps population values to a light-to-dark blue range, and each country includes an SVG title tooltip showing the name and population in millions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b6d6aa9c54d4921a8957df5f1153292?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
