{"version":"1.0","type":"rich","title":"World Map Visualization","description":"A choropleth world map colors countries according to population values loaded from a CSV file. The visualization uses d3.geoNaturalEarth1 for the map projection and d3.geoPath to render GeoJSON country boundaries. A d3.scaleQuantize with a d3.schemeBlues color range maps numeric population data to fill colors, while countries without matching data appear green. The example demonstrates loading external GeoJSON from a GitHub repository and joining CSV data to map features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b9524a47d7f340f283032c47054e5974?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
