{"version":"1.0","type":"rich","title":"Assignment_8_sowjanya_Network Visualization","description":"This network visualization displays cities and the weighted routes between them. It loads comma-separated values from two GitHub-hosted files—one for nodes, one for links—and renders them as an interactive force-directed graph. The layout is computed using `d3.forceSimulation` with link, many-body charge, center, and collision forces. Users can drag nodes, and hovering reveals a tooltip showing the city ID and regional group (`NA`, `EU`, `AS`). The map is drawn as SVG, with node colors assigned via a `d3.scaleOrdinal` scheme and link thickness scaled by weight.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/53608c10ba1d4f2487d40eba6d10e7d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
