This example reproduces a Sol LeWitt-inspired drawing by using SVG masks to create a circular boundary filled with two alternating sets of stripes: horizontal bands appear inside the circle’s center, while vertical bands cover the surrounding area. The code builds an SVG document directly via `document.createElementNS`, defines two masks (`circle-mask` and `circle-mask-2`) with a white circle and a black circle, respectively, and applies these masks to 100 horizontal and 100 vertical rectangles. No external libraries are used; all rendering is native SVG.
