This interactive visualization reproduces Sol LeWitt's geometric art using D3.js and raw SVG. It displays a grid of 100 gently wavy horizontal and vertical lines, each rendered in colors from D3's `scaleOrdinal` and `schemeCategory10`. Two circular SVG masks clip the intersecting line sets, creating two overlapping circle patterns in the center of the viewport. The code constructs SVG elements directly via `document.createElementNS` and uses D3 version 6.6.1 for color scaling.
