This example recreates Sol LeWitt’s horizontal line wall drawing using 30 overlapping black rectangles that fill the entire browser window. The SVG is created dynamically via the Document Object Model (DOM) API, with rectangle elements positioned at fixed vertical intervals and sized to the viewport’s width. The code uses `createElementNS` and `setAttribute` to generate the vector graphics, producing a minimalist, generative composition that mirrors the artist’s geometric style. No external libraries are required.
