This example demonstrates the minimal structure of an HTML document combined with a JavaScript visualization using D3.js v3. It shows a blank page with an empty body, serving as a starting point for embedding interactive graphics. The code loads D3 from a remote source and uses its core API to manipulate the Document Object Model (DOM) or SVG elements once the script executes, though no specific visualization is drawn here. The fork focuses on the foundational setup required for any D3-based chart, with the visualization logic left for the user to add.
