This visualization reproduces a Sol LeWitt art piece using D3.js, displaying a grid of horizontal and vertical thin rectangular bars across the full viewport. The bars are partially revealed through two circular masks, creating a geometric pattern of intersecting lines within a central circular region. Using d3.select and range, the code generates 100 rect elements in each orientation, applying SVG mask elements with contrasting black-and-white fills to selectively show vertical bars inside one circle and horizontal bars inside another. The rendering is entirely SVG-based, with the artwork adapting to the browser window dimensions.
