This example reproduces a Sol LeWitt art piece using SVG, displaying a central circle where horizontal and vertical lines intersect against a contrasting background. The circle is highlighted with yellow horizontal stripes, while the surrounding area features red vertical lines. The code uses raw SVG APIs to construct masks, specifically `createElementNS` for elements like `rect`, `circle`, and `mask`, defining visible regions. Horizontal stripes are masked by a white circle, while vertical lines use a rectangular mask with a transparent cutout, creating the layered geometric composition.
