This visualization generates a grid of thin horizontal and vertical black stripes across the full screen, inspired by Sol LeWitt’s wall drawings. It uses the SVG API to create repeating `<rect>` elements, with a circular `<mask>` applied to the horizontal bars so they appear only inside a centered ring, while the vertical bars remain unmasked. The page is a single HTML file with no external libraries, and it uses `document.createElementNS` to construct the vector graphic dynamically.
