This interactive visualization generates a geometric pattern inspired by Sol LeWitt’s wall drawings, filling the browser window with a single black rectangular vertical band against a blank canvas. The code builds the SVG graph using native DOM methods (createElementNS) rather than D3’s selection helpers, while D3 v7 is loaded but not actively used in the visible logic. The pattern is created by applying a black SVG mask to the rectangular stripe, with dimensions tied to the viewport’s width and height. The rendering is minimal and static, offering a direct homage to LeWitt’s systematic, rule-based aesthetic.
