An empty D3 page demonstrates the minimal structure required to begin a visualization: a single `index.html` file with a `<head>` title and an empty `<body>`. The example uses no JavaScript libraries or APIs, showing only the raw HTML scaffolding that D3 v3 would typically attach an SVG or canvas to. The included README links to an embedded YouTube video, suggesting context rather than runtime behavior. This fork isolates the starting point for any D3 project, with no data, rendering, or interaction.
