This example reproduces a Sol LeWitt–style drawing using native browser APIs. It renders a full-screen SVG canvas and draws a series of 100 vertical rectangles, each 10 pixels wide, evenly spaced at 20-pixel intervals across the viewport width. The code uses `document.createElementNS` to construct SVG `rect` elements and appends them directly to the document body, with dimensions derived from `window.innerWidth` and `innerHeight`. No external libraries are used; the visualization relies purely on vanilla JavaScript and SVG.
