{"version":"1.0","type":"rich","title":"MAP - CIRCLES","description":"This visualization maps the global spread of COVID-19 by showing arcs from origin to destination countries, with circles marking each origin point and labels identifying the source country. The arcs are colored by origin country using a categorical scale, while a text list on the side ranks countries by the number of outgoing transmissions. The code uses `d3.geoNaturalEarth1` for the projection, `d3.geoPath` to draw country boundaries and arcs, and loads geographic data from a TopoJSON world atlas alongside two CSV files containing transmission records.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/29ba97751c28423f8533f342226f8459?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
