This example uses D3.js to render a generative piece inspired by Sol LeWitt, creating a grid of horizontal and vertical lines that intersect on a full-screen SVG. It applies two SVG masks (`circle-mask` and `circle-mask2`) with inverted black-and-white circles to selectively reveal line segments, producing a layered, cross-hatched pattern with a circular focal point. The 100 rectangles in each direction are generated via `d3.range`, with attributes set through method chaining, and the resulting vector graphic is displayed entirely in the browser.
