This example generates a grid of horizontal and vertical stripes using 100 rectangles each, layered to create a woven pattern. Two SVG masks, one inverted, apply symbol shapes derived from D3's `symbol` API, casting the stripe pattern through alternating star-like forms. The code uses `d3.select`, `d3.range`, and `d3.join` to declaratively build the SVG elements within a React-free, vanilla JavaScript environment, with dimensions spanning the full window.
