This example presents a minimal HTML page that demonstrates the integration of CSS and JavaScript in a web browser. It serves as a bare-bones starter template, showing how to structure a simple document with styling and interactive behavior. The code uses basic DOM manipulation and event handling through vanilla JavaScript, with CSS selectors for visual presentation. This fork emphasizes the foundational setup, providing a clear, uncluttered starting point for building more complex visualizations or web applications. It does not utilize external libraries like D3 or React, keeping the implementation straightforward and accessible.
