This visualization reproduces a Sol LeWitt wall drawing using D3.js, rendering a grid of horizontal and vertical lines that are selectively masked by circular paths. The piece uses D3’s `select`, `range`, and `symbol` APIs to create 100 rectangles in each orientation, with the masks defined via SVG `mask` elements and D3’s path symbols. The full-viewport SVG canvas adapts to the browser window, and the `join` operation efficiently appends the graphical primitives.
