This example reproduces Sol LeWitt’s geometric art using an SVG rendering approach. It displays a grid of horizontal and vertical stripes, but only within a circular region at the center of the screen. The code creates SVG masks, specifically `circle-mask` and `circle-mask2`, to clip two sets of 100 rectangle elements. The first set uses a white-on-black mask for horizontal stripes, while the second uses a black-on-white mask for vertical stripes, producing a clean, intersecting pattern. The canvas automatically scales to the full window dimensions.
