This example reproduces a Sol LeWitt-inspired drawing using D3 selections and SVG masks. It renders 100 horizontal rectangles across the full window width, each masked by a circular cutout centered on the screen, creating a striped pattern with a visible circle. The code uses D3’s `select`, `selectAll`, `data`, and `join` methods to bind array data to SVG `<rect>` elements, and defines the mask via a hardcoded SVG `<mask>` element with a black background and white circle. The visualization runs in a React framework with a minimal HTML setup, relying on D3 v6.6.1 for DOM manipulation and SVG rendering.
