This example presents an empty SVG playground built with D3 v6, offering a blank canvas for creating and experimenting with vector graphics. The page loads the D3 library and establishes a CSS-styled body, while the accompanying JavaScript logs "Hello" and the D3 object to the console. It demonstrates a minimal setup for SVG-based data visualization, relying on D3’s core API and CSS for layout, with no pre-defined marks or data bound to the scene.
