{"version":"1.0","type":"rich","title":"D3 selection","description":"This example demonstrates a dynamic field of circles that continuously undulate across the screen, their positions and radii shifting over time. It displays a swarm of shapes moving in a wave-like pattern, driven by a sine function of time and index. The visualization uses the D3.js library’s `select` and `range` APIs to manage SVG elements, appending a full-screen SVG canvas. Through an animation loop using `setInterval`, it regenerates data at 60 frames per second, employing `selectAll` and `join` to efficiently update the existing circles’ attributes, creating a smooth, organic motion.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6d803d56ac3a4a56b2c09db5deea2ba9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
