This visualization reproduces a Sol LeWitt art piece using SVG elements and mask-based compositing. It shows a grid of horizontal and vertical stripes that intersect within a central circular region, creating a geometric pattern where line orientations alternate inside and outside the circle. The code uses raw SVG DOM manipulation via `createElementNS` to build rectangles and defines two masks (`circle-mask` and `circle-mask-2`) to control visibility. Horizontal stripes appear inside the circle, while vertical stripes fill the outer area, demonstrating how SVG masks can selectively reveal layered shapes.
