A full-screen D3 visualization reproduces Sol LeWitt’s wall drawing using 48 horizontal and 48 vertical striped rectangles. Two SVG masks, created with `d3.symbol` and the `symbols[0]` diamond path, define circular cutouts that invert the stripe pattern. The code uses D3 v7’s `select`, `range`, and `join` to generate elements, with the second mask rendered in opposite fill colors to create a contrasting central motif. Rendering is purely SVG-based without animation.
