Sol LeWitt’s geometric drawing system is recreated as a generative SVG composition using D3. Horizontal and vertical grid lines are drawn across the viewport, each filtered through one of two masks that reveal alternating symbol shapes from `d3.symbol` at fixed intervals. The masks are constructed with `d3.select` and `append`, using `d3.range` to place five distinct symbols, while the grid relies on `selectAll` and `join` with `rect` elements. This implementation adapts the artist’s rule-based aesthetics to a full-screen, code-driven format.
