This example renders a generative art piece inspired by Sol LeWitt, using D3 to create a full-screen SVG composition. It builds a circular mask and overlays alternating horizontal and vertical black bars, demonstrating SVG manipulation through DOM creation methods. The code uses the `selection` import from D3 and constructs elements like `circle`, `rect`, and `mask` programmatically, with the browser’s viewport dimensions determining the canvas size. The result is a geometric pattern that explores the interplay of positive and negative space.
