This example generates a full-screen generative artwork with a grid of alternating vertical and horizontal bar stripes, separated by a circular mask. Built with React and rendered as SVG, it uses D3’s `select` and `range` to append 100 rectangles in each direction, then applies two mask definitions (`circle-mask` and `circle-mask-2`) to invert the pattern inside and outside the circle. The result is a modern, interactive take on a Sol LeWitt drawing, where the composition depends on the browser window’s dimensions.
