{"version":"1.0","type":"rich","title":"Q1 module 8","description":"This example shows a simple choropleth world map of population for three countries: the United States, India, and China. A Mercator projection via `d3.geoMercator` and `d3.geoPath` renders the embedded GeoJSON polygons. Each country’s fill uses a sequential color scale with `d3.interpolateBlues` based on population values from an in-memory JavaScript object. Hovering reveals a tooltip with country name and population via SVG `<title>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ddf122d525024ce6b18424a897d631d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
