This example reproduces a Sol LeWitt-style geometric art piece using raw SVG and JavaScript. It shows a full-screen vertical grid of thin horizontal and vertical lines, with a central circular region highlighted by a mask. The rendering relies on the SVG `mask` element and dynamically created `rect` elements, using standard DOM APIs like `document.createElementNS`. The horizontal lines are clipped to a circle via the mask, while vertical lines span the full height, creating a layered, minimal composition.
