{"version":"1.0","type":"rich","title":"ICE-8 World Map.","description":"This choropleth map visualizes the world’s ten most populous countries by filling each nation with a color from a sequential YlGnBu scale. Population values, hard-coded in the page or loaded from a CSV, drive the color intensity, with other countries appearing in a neutral cream. The map is rendered using `d3.geoPath` with a Natural Earth projection, transforming geospatial data from TopoJSON into SVG paths. Tooltips show each nation’s exact population. The example uses D3 v7 and the `topojson` library for feature conversion.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dedb86a052ab4cce9047bacee906b69e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
