This example demonstrates the minimum requirements for an HTML page that integrates CSS for styling and JavaScript for basic interactivity. The page uses a `style` block to center the body text and set an extremely large font size, while inline `script` tags execute simple JavaScript commands. It includes a generic function definition and logs a message to the browser’s developer console, relying on the standard JavaScript `console.log` API. The example serves as a foundational template for building more complex visualizations without external libraries.
