Countries without data appear gray. Built with React and D3 v5, the visualization uses `geoNaturalEarth1` and `geoPath` to render country boundaries from World Atlas TopoJSON, with graticules and interiors drawn as separate SVG paths. Data is loaded from CSV files via D3's `csv` function, and country codes are matched to join the dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/920b1aac682e43489b8d0b55f6d21dcc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
