This visualization uses D3 v7 and Anime.js to generate an abstract, grid-based composition of colored vertical and horizontal bars. It shows a pattern of alternating purple and green vertical rectangles layered over black horizontal lines, with two circular SVG masks creating distinct circular cutout regions that reveal the different bar orientations. The code constructs elements via D3 selections and raw SVG DOM manipulation, applying masks to selectively show portions of the two bar layers.
