A force-directed network shows photographic collections and their creators, with nodes grouped into numbered items, catalog years, and photographer names. The visualization loads graph.json data and renders it as SVG using the D3 v3 force layout, with `d3.layout.force()` controlling node positions and link distances. Nodes display GitHub favicon images and text labels, while gray links represent connections with varying betweenness centrality values. The simulation updates positions on each tick, constraining nodes within the 960×500 viewport.
