This example is a bare-bones HTML page that displays a single heading with the text "asd." It demonstrates the minimal structure required for an HTML document, including the `<!DOCTYPE html>` declaration, `<html>`, `<head>`, and `<body>` elements, with a `<title>` in the head. The page uses no external libraries or custom styling, relying purely on the browser’s default rendering of standard HTML tags. The code shows the simplest possible setup for a web-based visualization or application, with no dynamic data or interaction involved.
