This example recreates a Sol LeWitt-style geometric composition using overlapping horizontal and vertical stripes. Two sets of SVG rectangles are drawn across the full width and height of the viewport, each filtered through a separate SVG mask. The masks reveal or hide portions of the stripes using a row of D3 symbol shapes (from `d3.symbol`), with one mask inverted. The visualization uses D3 v6 selections, `range`, and `join` to generate the elements, and renders entirely as SVG in the browser.
