A force-directed graph displays connections among a set of named nodes, with gray circles linked by straight lines. The visualization is built using D3 v7 and SVG, employing `d3.forceSimulation` to compute node positions and update the layout on each tick. Links represent relationships from a fixed array of source-target pairs, while the code also includes a commented-out CSV loader for potential data import. Node and link styling is defined in an external stylesheet.
