This example reproduces a Sol LeWitt art piece using pure SVG rendering. It generates 100 horizontal and 100 vertical rectangular strips that are clipped by two circular mask regions, creating a grid-based geometric composition. The visualization relies on D3.js v7 methods including `select`, `append`, `range`, and the `join` operator to efficiently create SVG elements. Two SVG masks (`circle-mask` and `circle-mask-2`) define the visible areas, with the first mask using a black rectangle and white circle, while the second inverts this pattern to achieve the final layered effect.
