This force-directed graph maps the U.S. electrical grid, showing three interconnections, six generation types, and five independent system operators linked by transfer capacity. Nodes are positioned using physics-based simulation, while link thickness encodes capacity in gigawatts and node color distinguishes type. The network is built with D3.js v7, using the `d3.forceSimulation` API on an SVG canvas, and supports interactive node dragging for exploration. Metadata indicates the layout derives from a v3 source file, with styling applied via CSS for node strokes and label typography.
