{"version":"1.0","type":"rich","title":"flow chart 1","description":"This flow chart visualizes the early-stage spread of a virus between global locations, with arcs drawn between paired longitude and latitude coordinates from a CSV file. The map uses a Mercator projection and displays the geographic network of transmissions, highlighting China’s provinces as primary carriers to other regions. Built with D3.js v4, the visualization renders SVG paths for both the world map and the connection lines, using `d3.geoMercator`, `d3.geoPath`, and `d3.csv` to load and project the data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4af1677a6d59438d9849b8a45a3f85d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
