{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"A choropleth world map visualizes population data for select countries, using a red sequential color scale to encode values and a legend for reference. Built with D3 v7 and TopoJSON, it uses `d3.geoPath` and `d3.geoNaturalEarth1` for projections, loading country boundaries from a world-atlas package and population values from a Gist JSON file. Hovering over a country reveals a tooltip with its population in millions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d9d3151608244cf2b320748e3016e557?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
