{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"A dynamic animation shows fifteen circles moving in a sine-wave pattern across the screen, with their radii oscillating over time. The example uses D3 v7’s `select`, `range`, and data joins (`join`) to bind and update SVG circle elements every frame, driven by `setInterval` at roughly 60fps. A static green rectangle anchors the composition, while circle positions and sizes are computed from a time variable `t`, demonstrating basic D3 transitions and SVG rendering without external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d064469d1f14a109e5605eedc823b19?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
