A minimal web page demonstrates the fundamental structure of HTML, CSS, and JavaScript working together. The example renders a single "Hello World" heading in the browser, illustrating the basic anatomy of a document with a `<head>` and `<body>`. The code uses raw HTML elements, such as `<h1>`, without any external libraries or data sources. This serves as a bare-bones starting point, contrasting with the linked React Starter example that introduces component-based frameworks for more complex visualizations.
