This example reproduces a Sol LeWitt-inspired drawing using D3.js, rendering a grid of horizontal and vertical black-and-white stripes on an SVG canvas. The SVG is populated with 100 rectangles in each orientation, using D3’s selection and `join` API to bind data to elements. Two circular masks, defined in D3’s `append` and `attr` calls, clip the stripes so that only a central circular region is visible, creating a geometric optical effect against the full-screen canvas.
