{"version":"1.0","type":"rich","title":"Sol LeWitt Exercise 9 x 4","description":"This example recreates Sol LeWitt's Exercise 9 x 4 using randomly generated SVG rectangles, circles, and polygons. The code shows vertical and horizontal black-and-white striped bands with varied widths, layered over circular arc patterns that shrink in radius from the canvas edges toward the center. It uses the raw DOM API `createElementNS` to construct SVG elements, including masks that define which parts of the layered shapes remain visible. All geometric values, such as stripe widths and circle offsets, are derived from the `getRandomInt` and `offset` functions, producing a near-regular grid with subtle irregularities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
