{"version":"1.0","type":"rich","title":"World Map – ICE-8","description":"This choropleth map visualizes global population data using a Mercator projection and color-encoded country values. D3 v7 loads GeoJSON world boundaries and CSV population data via `Promise.all`, then applies a sequential `d3.scaleSequential` with an `interpolateYlGnBu` color scheme. The code uses `d3.geoPath` and `d3.geoMercator` to render SVG paths, and displays a linear gradient legend with an axis. Countries lacking population data render in gray, while hover tooltips provide country names and values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03f577cf8bde49c49de6583cc32a2208?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
