This example shows a small network of photographic records, visualized as a graph where nodes represent photo IDs and people (like James Anderson and Francis Bedford), connected by edges that indicate associations. The code transforms the original links into curved path connections via intermediate nodes, rendering them as SVG paths. It uses `d3.forceSimulation` with link, charge, collide, and center forces to lay out the graph, and `d3.drag` for interactive node movement. Node colors map to groups using `d3.scaleOrdinal` with `d3.schemeCategory20`.
