This example reproduces a Sol LeWitt art piece using raw SVG elements. It generates 100 vertical rectangles, each 10 pixels wide, that span the full height of the viewport. A circular mask, centered on the screen with a 200-pixel radius, limits the visible portion of these bars, creating a clean, geometric composition. The code uses the SVG `mask` element and dynamically creates rectangles and the circle via standard DOM APIs, with no external libraries or data sources.
