This example reproduces a Sol LeWitt-inspired geometric composition using two overlapping sets of thin horizontal and vertical rectangles. The drawing applies two distinct SVG masks to each set, creating a crosshatched grid that visually inverts where the shapes intersect. Built with D3 v6, it generates 100 rectangles per axis using `range` and `selectAll().join()`, while the `symbol` API draws a diamond-shaped mask path. The final SVG adapts to the full browser window size, with masks rendered through appended `<mask>` elements.
