This example reproduces a Sol LeWitt-style geometric composition using D3.js. It draws 100 horizontal and vertical alternating rects across the full viewport, both filtered through SVG masks to create overlapping circular cutout effects. The code uses D3 selections, `range`, and `join` to generate the rectangles, with custom `mask` elements defining the circles. The SVG rendering approach relies on D3 v7 and JavaScript to programmatically construct the artwork.
