A fork of a Sol LeWitt reproduction uses D3 to render intersecting horizontal and vertical line bands, each filtered by a mask that reveals a row of geometric symbols. The code generates 100 rectangles per axis, spaced at 20-pixel intervals, and applies separate masks created with D3’s `symbol` and `symbols` API. The SVG output relies on D3 selections, `range`, and mask definitions to alternate inverted fills, producing an abstract, generative pattern across the full viewport.
