This example reproduces a Sol LeWitt-inspired geometric composition using D3.js with SVG rendering. It displays a grid of horizontal and vertical lines that are partially masked by two overlapping shapes, creating a layered visual effect. The code uses `select`, `range`, and `join` to generate the line elements, while `symbol` and `symbols[1]` define a star-shaped mask. A second circular mask further modifies the visibility of the lines, producing an intricate interplay between the drawn paths and the masked regions.
