This visualization shows a network of nodes connected by lines, resembling a phone call graph, where each node likely represents a person or device. The layout is computed using D3 v5’s `d3.forceSimulation` with force-directed positioning. The SVG rendering is driven by React, with the graph drawn inside an SVG element. The page includes a clickable phone number link, and the data structure is defined in JavaScript, with styling provided by a separate CSS file.
