A generative geometric composition inspired by Sol LeWitt uses D3 v7 to render black bars across the full window. The SVG defines two masks—a circle and a star—and applies them to alternating horizontal and vertical bar groups, creating intersecting line patterns. `d3.range` and `d3.symbol` generate the shapes, while `select` and `join` manage the 100 rects per axis. The result is a minimal, modular artwork built entirely with scalable vector graphics.
