This example generates a full-screen SVG visualization inspired by Sol LeWitt’s geometric wall drawings. It creates 100 vertical rectangles, each 20 pixels apart and 10 pixels wide, spanning the entire height of the viewport using the `window.innerWidth` and `window.innerHeight` properties. The code directly manipulates the SVG DOM via `document.createElementNS` and `setAttribute`, appending the shapes to the page without any external libraries or data sources.
