This example generates a full-screen abstract composition by dynamically creating an SVG scene using the DOM API. It shows one hundred vertical rectangles, each 10 pixels wide, spaced 20 pixels apart across the viewport width, extending the full window height. The code uses the raw `document.createElementNS` method to build SVG `rect` elements without any external libraries, setting the SVG dimensions to the browser's `innerWidth` and `innerHeight`. The script then appends each rectangle sequentially, producing a rhythmic grid of uninterrupted lines.
