This example generates a dynamic geometric composition inspired by Sol LeWitt, where alternating vertical and horizontal stripes are clipped by two overlapping circular masks. Using D3.js version 6 in a React-free SVG environment, the code defines two masks with inverted fills, then applies them to striped rectangles created via `d3.range` and `d3.join`. The result is a clean, monochrome interplay of lines and shapes, rendered purely with SVG elements on a full-window canvas.
