{"version":"1.0","type":"rich","title":"Fork of React & D3 Starter","description":"A force-directed network diagram visualizes flight routes among seven cities, with node size reflecting degree centrality and color mapping to geographic region. The visualization uses D3 v7's `forceSimulation` with `forceLink`, `forceManyBody`, `forceCenter`, and `forceCollide` to position nodes, while SVG circles, lines, and text labels render the graph. Interactive drag behavior is implemented via D3's `drag` function, and a legend identifies the four region categories. The data originates from a hardcoded JavaScript array of city nodes and weighted route links.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1d2a372da374992ada2ed5f88a2958b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
