{"version":"1.0","type":"rich","title":"Fork of Flow chart for the spread of COVID-19 across the world","description":"This visualization is a flow map that traces the early spread of COVID-19 between geographic locations, highlighting how provinces in China acted as initial carriers before secondary travel to Europe and Australia. The map uses a Mercator projection and renders a grey world map with green curved paths representing each connection. Built with D3 v4, it loads GeoJSON world boundaries and CSV coordinate data, then uses `d3.geoPath` to draw both the map and the line-based routes. The underlying data comes from the provided `data.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e251ff41d7ea4415968ff5a6b0e9f93d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
