This example demonstrates a full-screen SVG visualization composed of 100 horizontal rectangles, each 10 pixels tall. The rectangles are rendered as uniform stripes that collectively fill the entire browser viewport. The visualization applies a circular mask to every rectangle, creating a repeating pattern of clipped shapes. The code uses D3 v6's `d3.select` and `.join` APIs to efficiently bind array data to SVG elements, with `d3.range(n)` generating the sequence of y-positions.
