This visualization reproduces a Sol LeWitt art piece using D3 v6, rendering 100 horizontal and 100 vertical rectangles as SVG elements. The rectangles are masked to reveal only a circular region at the center of the canvas, creating an overlapping grid pattern reminiscent of the original work. The code uses D3’s `select`, `range`, and `join` methods to bind data and generate the SVG shapes, with two `mask` definitions controlling the visibility of the crossing bars.
