{"version":"1.0","type":"rich","title":"Week 7 Country Map - Nobel Prize Winners","description":"This visualization shows the global distribution of Nobel Prize winners by country, using prize counts derived from laureate birth or organization countries. A choropleth world map colors each nation on a blue sequential scale, with gray for countries lacking winners and a tooltip providing details. The implementation uses D3 v7 with `d3.geoNaturalEarth1` and `d3.geoPath` to render SVG paths from world GeoJSON data, while `d3.rollup` and a custom normalization function reconcile country names between the CSV dataset and map features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dfa78c8e0bc843c4a74429d82a474142?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
