This visualization recreates Sol LeWitt’s geometric art by using alternating horizontal and vertical bars to form a grid-like pattern. The bars are masked by two overlapping shapes—a circle and an inverted circle—which create intersecting voids in the composition. The code relies on D3’s `select`, `range`, `symbol`, `symbols`, and `mask` APIs to generate SVG elements dynamically. The layout is calculated from the viewport dimensions, and the rendering is entirely SVG-based with no external data source.
