This example demonstrates the most minimal possible integration of JavaScript with HTML, showing a page that renders the text "Hello HTML" and executes a JavaScript script that logs "Hello, JavaScript!" to the console. The code uses a plain HTML document with a `<script>` tag referencing an external `script.js` file, which contains a single `console.log` call. This serves as a foundational template for understanding how CSS and JavaScript can be embedded within web pages, and it provides a starting point for more complex React-based visualizations.
