Hello HTML
This example generates a neat grid of fifty black squares on a plain white page. Using a simple `for` loop, it creates and appends `div` elements directly to the document body, styling them with CSS flexbox and border-radius for a rounded look. No external libraries are involved, relying solely on native JavaScript DOM manipulation and CSS to produce the static, evenly spaced visual pattern. The result is a minimal, purely HTML-based composition demonstrating basic procedural generation.
