This example reproduces a Sol LeWitt-inspired drawing using raw SVG and JavaScript, without any external libraries. It renders 100 vertical rectangles, each 10 pixels wide, spaced 20 pixels apart, and filling the full height of the browser window. The rectangles are created dynamically in a loop using the `document.createElementNS` API and appended to an SVG element whose dimensions match `window.innerWidth` and `window.innerHeight`. The resulting pattern demonstrates a minimalist, systematic grid-based composition directly in the browser.
