A tiled grid of horizontal and vertical bars forms a minimalist composition, overlaid with two masks that reveal and hide sections using d3 symbols as cutouts. The visualization uses D3 v6 with select, range, symbols, and symbol to generate SVG shapes, while mask elements with rect backgrounds and symbol paths create the interlocking positive and negative spaces. The code builds two masked layers to produce a Sol LeWitt-inspired geometric interplay, rendered at full screen with no interaction.
