This force-directed graph displays the connections between nodes in a network, fetched from a remote text file. The visualization uses D3's `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` forces to position nodes, and `d3.drag` enables interactive node manipulation. The graph is rendered as an SVG with circles, where hovering reveals node IDs. The layout dynamically updates on each simulation tick, and the data is parsed from a plain text file containing source-target pairs.
