{"version":"1.0","type":"rich","title":"making map ","description":"This example shows a choropleth world map of population by country for 2022, with each country shaded according to its population using a sequential blue color scale. Countries with no data appear in light gray. The visualization loads population data from a GitHub-hosted JSON file, then uses `d3.json` to fetch country geometries from the world-atlas package, applies a Natural Earth projection with `d3.geoNaturalEarth1`, and renders the map as SVG paths via `d3.geoPath`. Tooltips display exact population values for each country.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d4cb8566cc04a03a7a5864d36b58ecf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
