{"version":"1.0","type":"rich","title":"Fork of Chloropleth","description":"This fork of a choropleth combines a geographic map with a scatter plot, both rendered as SVG. The map colors countries by birth rate using a linear scale, while the scatter plot displays fertility rate against life expectancy, with circle size encoding population and color representing continent via an ordinal scale. The code uses `d3.geoEqualEarth`, `d3.geoPath`, and `d3.axisBottom`/`d3.axisRight`. Data comes from a GeoJSON file, a CSV of world statistics, and a JSON continent mapping, all loaded with `Promise.all` and `d3.json`/`d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d70f51b6dc364bbd8a6c5b06c932e4ca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
