This example reproduces a Sol LeWitt-style wall drawing as an interactive web page. It displays a grid of horizontal and vertical stripes that are partially masked by two circular cutouts, creating a layered geometric pattern inspired by the artist’s work. The visualization uses D3.js (version 6.6.1) to select the body and append an SVG canvas, while the mask and rectangle elements are created directly with the Document Object Model (DOM) APIs, with `mask` and `mask2` applied to the stripe layers.
