{"version":"1.0","type":"rich","title":"Concentric circles","description":"The visualization displays a radiant, multi-hued field of concentric circles that emerge from a central point and spiral outward against a rainbow gradient background. Each circle’s size and color vary randomly, creating a dense, organic pattern. Built with React and rendered as SVG, the code maps over 50 indices and 50 pixel offsets, calculating each circle’s position using trigonometric sine and cosine functions. A radial gradient defined in the SVG `defs` section fills every circle, while a drop-shadow filter adds a cyan outline for depth.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bf5aec19f5c4c199eaff49cceaa0a39?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
