A grid of alternating black and white horizontal and vertical bars forms a woven pattern, with a circular mask revealing a black star shape on one layer and a white star on the other. The visualization uses a D3 SVG rendering with two masked rectangle groups, each drawn from 100 equally spaced strips. The masks combine a full-screen rect with a `d3.symbol` path of type `symbols[1]`, translated to the center, to create the contrasting star overlays.
