This example recreates a Sol LeWitt art piece, drawing 100 horizontal and 100 vertical rectangles across the entire viewport. It shows the interplay of overlapping lines masked to reveal a circular void in the center, where the horizontal bands cut through a white circle and the vertical bands appear around a black circle. The visualization uses D3 v6 selection methods and joins, with SVG mask elements, `range`, and `join` to bind data and render the geometric composition.
