{"version":"1.0","type":"rich","title":"Sol Lewitt Circle Animated","description":"An animated SVG composition recreates Sol Lewitt’s circle drawings by layering two sets of thin, colored lines. Vertical lines and horizontal lines are drawn as rectangles, each clipped by a circular mask that alternately reveals or hides the center. The line thickness and spacing incrementally increase each frame, cycling from fine grids to bold strokes. The animation uses raw `document.createElementNS` for SVG elements, `window.requestAnimationFrame` for looping, and masks defined with `url(#mask-id)`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/20a430225c104662855bf110aa76b481?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
