This example reproduces a Sol LeWitt-inspired geometric composition using layered SVG elements and D3.js. It draws a grid of horizontal and vertical rectangles across the full viewport, with each line partially masked to create intricate overlapping patterns. The visualization uses D3’s `select`, `range`, `symbols`, and `symbol` APIs to generate two masks containing circular, triangular, and other symbol shapes. These masks apply inverse fill logic—one inverting the grid’s visibility—producing a dynamic interplay between the background lines and foreground symbolic cutouts. The rendering relies entirely on SVG attributes like `mask` and `fill`.
