This example renders a generative composition inspired by Sol LeWitt using raw SVG creation via JavaScript. It constructs a full-screen SVG and uses two masks to create a circular cutout: one mask reveals vertical stripes outside the circle, while another reveals horizontal stripes inside it. The code manually creates SVG elements using the `document.createElementNS` API and sets attributes directly, without using any external libraries. The result is a static, geometric pattern of 100 vertical and 100 horizontal rectangular stripes that alternate based on their position relative to the central circle.
