This example renders a vertical Sol LeWitt-inspired composition using raw SVG and JavaScript. It creates 100 rectangle elements, each 10 pixels tall and spaced 20 pixels apart, stacked vertically across the full width of the browser window. The rectangles are appended directly to an SVG element created via the Document API, with the total canvas size determined by `window.innerWidth` and `window.innerHeight`. No additional libraries are used; the code relies solely on native DOM manipulation and SVG attributes.
