This example demonstrates a minimal HTML page that integrates CSS and JavaScript to display a heading and log a message to the browser console. The code uses basic DOM elements and an embedded script to output "Hello JavaScript!" while also triggering an alert via the external `java.js` file. Styling is applied through both an external stylesheet (`info.css`) and inline `<style>` tags, setting the heading’s colors. The visualization relies on plain HTML and JavaScript APIs, with no external libraries or data sources.
