This example presents a minimal D3.js (v6) SVG rendering of a 10-node network graph, where the nodes (A–J) and their links are defined in a JSON object embedded within the JavaScript source. The code selects the existing `<svg>` element, sets a green background, and appends a transformed group, though the graph nodes and edges are not actually drawn in the provided bundle.js. It demonstrates the basic structure for setting up an HTML page with D3, using the `select` function and SVG attribute chaining, but stops before visualizing the data.
