This graph displays the relationships among various programming languages, with nodes connected by curved paths indicating their associations. The layout is generated using a force-directed simulation with `d3.forceSimulation`, `d3.forceLink`, and `d3.forceManyBody`. Nodes are draggable, and the visualization updates in real-time via the simulation’s tick event, rendering SVG circles and text labels. The code defines links from an inline dataset, where each connection includes a source, target, and value, though the value is not used in the final rendering.
