This force-directed graph visualizes relationships between programming languages as a network of labeled, colored nodes connected by curved links. It uses `d3.forceSimulation` with link, center, and many-body charges to compute node positions, while each node’s radius and blue color intensity scale with its degree (weight). Links are styled differently based on a binary value: dashed black lines indicate zero, solid green lines indicate one. The chart is rendered as an SVG using d3.v5.
