This piece reproduces a Sol LeWitt wall drawing as a slowly shifting field of black lines on a white background. The lines bend and scroll continuously as their endpoints follow animated paths, creating a dynamic, generative composition. The code uses `d3.forceSimulation` to compute the evolving positions of the line vertices, with `requestAnimationFrame` driving the redraw of the SVG elements. It relies on d3.v7 and the DOM directly, with no external data source beyond the geometric rules of the artwork.
