A Sol LeWitt-inspired generative artwork fills the browser window with a grid of overlapping horizontal and vertical bars. The piece uses two SVG masks—one revealing a central circle through dark stripes, the other inverting the effect—to create a dynamic interplay of lines and negative space. Built with D3 v6, the code leverages `select`, `range`, and data joins to render 100 rectangles in each direction, with mask elements defining the circular focal point. The result is a precise, minimalist composition that echoes LeWitt’s geometric aesthetic while demonstrating D3’s declarative SVG manipulation.
