D3
This example sets up an empty SVG canvas and appends it directly to the body, demonstrating a minimal starting point for D3-based visualization in a React-free HTML page. The code uses the d3-selection module via `select` to create the SVG element with fixed width and height attributes. It relies on D3 version 6.6.1 as the sole dependency, with the page structure defined in a simple HTML file that loads a JavaScript entry point. No data or visual marks are rendered, making it a bare-bones template for further development. The styling uses CSS for a large centered message, though no content is displayed in the body.
