This example reproduces a Sol LeWitt-inspired geometric composition, generating a grid of overlaid horizontal and vertical stripes that are masked to reveal a central circle. The visualization uses D3 v6 to create an SVG scene, drawing 100 rectangles in each orientation and applying two masks with contrasting black-and-white circular cutouts to shape the final pattern. The rendering fills the entire browser window, with the circle positioned at the center of the viewport.
