This visualization uses raw SVG and JavaScript to reproduce a Sol LeWitt wall drawing. It layers 100 horizontal and 100 vertical rectangular stripes across the full browser window. A circular mask, created via SVG `mask` and `circle` elements, is applied only to the horizontal lines, revealing them solely within a central 200-pixel radius. The code dynamically sizes the artwork to the viewport dimensions, using `document.createElementNS` and `setAttribute` to build the composition without any external libraries.
