A force-directed network diagram visualizes a graph of ten named nodes connected by red links. The visualization uses `d3.forceSimulation` with a link force, a many-body charge force set to -1300, and a center force to position the nodes. Each node is rendered as a white circle with a red stroke, labeled with its name and placed using the simulation's `ticked` event. The graph loads its data from a `flare.json` file containing node and link definitions.
