This generative art piece reproduces a Sol LeWitt-inspired composition, displaying a grid of horizontal and vertical black stripes across the full browser window. The work shows a circular region in the center where the horizontal stripes are masked out, revealing only the vertical lines, creating a distinct visual inversion. The piece uses raw SVG elements created via the Document API, employing a `mask` element with a white circle on a black rectangle to selectively hide parts of the rendered rectangles. The code iterates 100 times to generate both the horizontal and vertical stripe sets, relying on `window.innerWidth` and `window.innerHeight` to adapt the layout to the viewport size.
