This example visualizes a network of interconnected nodes and edges using D3.js. The graph employs `d3.forceSimulation` to position nodes and links, with paths rendered as thick, rounded lines in a dark teal color against a white background. The visualization demonstrates a force-directed layout, where the simulation calculates node positions and link paths dynamically. It uses SVG paths with `stroke-linejoin` and `stroke-linecap` set to round for smooth connections, while the `styles.css` file defines the visual styling for the lines and their paths.
