A large SVG displays horizontal and vertical stripes created from 100 rectangles each, layered with two circular masks. The overlapping masked striping produces a radial, sunburst-like pattern centered on the canvas. Built with D3.js, the code uses `range`, `selectAll`, and `join` to generate the bars, while `symbol` and `symbols` define the circular mask paths. The viewport is sized dynamically to the browser window.
