This example reproduces a Sol LeWitt-style drawing using only JavaScript and the Document Object Model (DOM). It generates a full-screen SVG canvas and fills it with 100 vertical rectangles, each 10 pixels wide and spaced 20 pixels apart, creating a rhythmic, wall-like grid pattern. The code uses `document.createElementNS` to construct SVG elements directly, without any external libraries, and sets the canvas dimensions to the browser window’s inner width and height. The rendering is purely algorithmic, based on a loop that iterates through horizontal positions, with no external data source.
