This example generates a striped pattern of 100 horizontal rectangles that cover the full width of the viewport, creating a simple optical art effect. A circular SVG mask is defined with a black circle, though the mask is not applied to the rectangles in the code. The visualization uses raw SVG APIs—`document.createElementNS` for elements and `setAttribute` for properties—rather than a library, producing an abstract, minimalist composition inspired by Sol LeWitt’s wall drawings.
