HTML Starter
This example demonstrates a minimal HTML page that uses D3 v5, loaded from a CDN, to render a single styled `<div>` element containing placeholder text. The code sets up a basic document structure with a large centered body font and a bordered box, showing how to integrate D3 into a plain HTML page without any additional frameworks. It highlights the core pattern of combining standard HTML elements with D3’s script tag inclusion, serving as a foundational template for more complex visualizations.
