This force-directed graph visualizes relationships between programming languages, with nodes sized by degree and colored on a blue scale. Links appear either green and thick or black and dashed, indicating a binary attribute. The visualization uses d3.forceSimulation to compute the layout, d3.forceLink for link forces, and d3.forceManyBody for repulsion. Node dragging is enabled via d3.drag. The SVG rendering is built dynamically, with curved paths for connections and labels positioned above each node.
