This example reproduces a Sol LeWitt-style drawing using procedural SVG. It first draws a series of vertical black rectangles across the full viewport, then applies an SVG mask containing a white circle over a black background to hide a central circular region. Horizontal strips are then drawn across the entire width, with the mask revealing only the area inside the circle, creating an intersecting grid pattern. The visualization uses raw JavaScript with the SVG DOM API to create elements dynamically, reacting to the browser window’s dimensions.
