{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This example displays a choropleth map of the world, coloring countries by their sample population values using a sequential blue color scale. The map is rendered with SVG and D3.js’s `d3.geoMercator` projection and `d3.geoPath`. It loads real world geometry from a local GeoJSON file (`countries.geo.json`) and overlays tooltips via SVG `title` elements. Population data is provided as a static JavaScript object, with missing countries shown in gray.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cdf57af783ff4d8fb0c5f7600d132e2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
