This is a minimal SVG playground template using D3.js v6, showing a simple “Hello!” message in the browser. It includes an HTML page that loads the D3 library through a CDN, a CSS file setting the body font size to 32px, and a JavaScript file that logs “Hello” and the D3 object to the console. The example demonstrates the basic scaffolding for building SVG-based visualizations, with the main script currently containing only setup code and no actual data-driven rendering.
