This example reproduces a Sol LeWitt-style artwork using an SVG mask to reveal a series of horizontal stripes inside a central circle. The visualization creates 100 rectangles, each 10 pixels tall, spanning the full width of the viewport, while a circular mask restricts their visibility to a 200-pixel-radius disc at the center of the screen. The code constructs the SVG dynamically via the DOM API, appending elements with methods like `createElementNS` and `setAttribute`, without relying on external libraries. The result is a clean, generative geometric composition that highlights the interplay between simple shapes and masking.
