This example renders a dynamic, animated reproduction of a Sol LeWitt art piece using D3.js. The visualization fills the entire browser window with a grid of thin horizontal and vertical rectangular stripes, each masked to reveal a series of large geometric symbols such as circles and stars. The piece uses D3’s `select`, `range`, `join`, and `symbol` APIs to generate the SVG shapes, while CSS keyframe animations cycle the background gradient. The masks are constructed with `symbol` paths, and the code references `window.innerWidth` and `window.innerHeight` for the canvas size.
