This example reproduces a Sol LeWitt-style geometric composition using D3 version 7.8.2, rendering to an SVG canvas that fills the browser window. The code constructs an array of 100 rectangle marks, each intended to span the full width with a specific height and a circular mask, though the current implementation leaves the mark objects empty. It demonstrates data binding through `selectAll` and `join`, applying positional and masking attributes to each rect. The rendering approach relies on SVG elements and the `d3.select` API.
