{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"A dynamic array of circles undulates across the canvas, with each circle's vertical position and the total count oscillating sinusoidally over time. The animation is built using D3.js's `select`, `range`, and chained `join` operations to update the SVG elements. The code runs a 60 FPS interval, recalculating data from a sine function and merging new circles with `selectAll('circle').data(data).join('circle')`, while styling each with a fixed radius of 20 pixels. The rendering relies on SVG attributes (`cx`, `cy`, `r`) updated per frame.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99522b47d238428f857d47be974fb67a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
