This example demonstrates a simple interactive HTML page where clicking on text triggers a change in its content. The page displays the phrase “my text” at a large font size, and when clicked, the text updates to “I have changed” using JavaScript. The implementation uses plain HTML, inline CSS for styling, and a JavaScript arrow function assigned to the `onclick` event handler, which accesses the element via `document.getElementById`. No external libraries are used, making it a minimal starter template for web visualization projects.
