This example reproduces a Sol LeWitt-inspired artwork as an interactive full-screen SVG visualization. It displays alternating vertical and horizontal colored bands that are masked to reveal a circular cutout in the center of the canvas, creating a geometric interplay between line directions. The vertical stripes use a gold-to-red linear gradient, while the horizontal stripes are rendered in the default black. The piece is built entirely with raw SVG DOM manipulation via `createElementNS`, using SVG `<mask>` elements and `linearGradient` definitions to achieve the visual effect without any external libraries.
