{"version":"1.0","type":"rich","title":"Wave with gradient","description":"This example animates a growing wave of circles across the screen, with each circle’s size and vertical position modulated by a sine function over time. The circles are colored with a radial gradient that transitions from purple to white. Written in D3.js, the code uses `select`, `range`, and a join to append new circles each frame, while `transition` and `easeLinear` control the size change. The animation runs on a `setInterval` at 60fps, incrementally adding circles until they fill the viewport width, then resetting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/206ca11520294731b2d119e43a72bbb3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
