This example demonstrates a minimal setup for starting a D3 version 7 project, rendering an empty SVG viewport with a green border. The code loads D3 from a CDN and uses `d3.select` to reference the body and SVG elements, though no data is bound or shapes are drawn. It includes a YouTube tutorial link for guidance. The rendering approach is SVG, with the `viewBox` attribute defining a 100-by-100 coordinate system, and the script is split between an HTML file and an external `bundle.js`.
