This example demonstrates a minimal D3.js v7 starter template, rendering an empty SVG canvas that is ready for custom visualizations. The code uses the D3 selection API (`d3.select`) to access the SVG element and reads its `width` and `height` attributes as numeric values. A separate `bundle.js` file is loaded after the main script, though no drawing operations are performed in the visible code. The page is styled with large, centered text and embeds a YouTube tutorial video.
