This example generates a full-screen composition of horizontal bars, using D3.js to create SVG rectangles that tile the viewport. The visualization relies on D3’s `select` and `append` API to build the SVG structure dynamically. The pattern resembles Sol LeWitt’s wall drawings, with a straightforward, systematic placement of bars. The code includes commented-out mask and circle elements, though these are not active in the final render. The result is a clean, generative graphic that adapts to the browser window size.
