{"version":"1.0","type":"rich","title":"Untitled","description":"A tiny SVG viewport shows 1,000 randomly placed circles bouncing and wrapping around its edges, with a live frames-per-second counter in the corner. The animation runs through `d3.timer`, updating each circle’s `cx` and `cy` attributes based on randomized velocity values. All rendering uses SVG elements and D3’s data join, with positions recalculated on every tick to keep the motion continuous.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a8181861259b42dbaa64b07ed5b5ee92?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
