A generative art visualization reproduces a Sol LeWitt–style composition using D3.js. It draws 100 horizontal rect elements across the full screen, each 10 pixels tall, with all shapes clipped through an SVG mask containing a single white circle on a black background. The mask reveals only the circular central region of the striped pattern, isolating the lines within a round frame. The example uses d3.select, d3.range, and selection.join to create the rects and mask elements, rendered as inline SVG.
