A blank SVG canvas primed for D3 visualizations, this example provides a minimal HTML page that loads D3 v5 from a CDN and includes an empty stylesheet. The page sets up an SVG element with fixed dimensions and an empty script tag, ready for user code. It demonstrates the foundational structure for starting any D3 project, using the d3-selection API implicitly through the SVG element, while the linked styles.css and index.html show how to organize a basic web setup.
