{"version":"1.0","type":"rich","title":"Circles09","description":"Circles09 displays a field of 1,197 translucent, colorful circles on a dark background, each colored by hue according to its index. The circles are arranged in a rotating, pulsing pattern that intensifies over time. The animation is built with d3.select, d3.range, and SVG circle elements, positioned via trigonometric functions (Math.cos, Math.sin, Math.tan) within a transform. The code uses a tributary.init and tributary.run loop to update the circles' positions, with constants like alien_factor and alien_factor2 controlling the spatial distortion and rotation speed.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-9413869?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
