This example uses D3.js in a React framework to generate an abstract geometric composition inspired by Sol LeWitt. It renders 100 horizontal and vertical rectangles as SVG elements, layered with two masking shapes—a star and a plus symbol—to create intersecting patterns. The code leverages D3 selections, `range()`, and `symbol()` to generate the shapes, while SVG masks control which parts of the grid remain visible. The visualization adapts to the full browser window and demonstrates a modular approach to procedural art.
