This example recreates Sol LeWitt’s geometric wall drawing using overlapping horizontal and vertical striped bands. A central circle is isolated through two SVG masks: one shows the horizontal stripes inside the circle, while the other reveals vertical stripes outside it. The code builds the SVG entirely via native DOM methods like `document.createElementNS` and `setAttribute`, with no external libraries. Each stripe is a thin rectangle, and the masks are defined with black-and-white fill patterns to clip the 100 stripes per direction.
