{"version":"1.0","type":"rich","title":"q2-2","description":"An interactive network diagram displays flight routes among eight U.S. cities, with nodes colored by geographic region (East Coast, West Coast, South). The visualization uses D3 v7's `forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to position nodes, while `d3.drag` enables user repositioning of cities. Links represent connections between city pairs, and a legend explains the regional color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a5e32b1a48648d398bb5197e208b8a5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
