A bare-bones HTML page demonstrates the minimal structure of a web document. The example contains only the standard `<!DOCTYPE html>`, `<html>`, `<head>`, and `<body>` elements, with a `<title>` tag reading "Hello HTML". No external libraries or JavaScript APIs are used, and the body is empty. It serves as a starting point for any web-based visualization by showing the simplest valid HTML skeleton that can later be extended with D3.js, Canvas, or other rendering tools.
