{"version":"1.0","type":"rich","title":"Fork of D3 Selection Exploration","description":"A looping animation renders a row of colored circles that undulate and change radius over time while a black line traces their connected path. The example demonstrates D3’s data-join and selection methods, using `selectAll` and `join` to update SVG circles and a `d3.line` generator for the path. Circle positions and sizes are computed from sine functions, with colors shifting through a custom shading function. The animation runs at 60 frames per second via `setInterval`, and the SVG canvas fills the browser window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b9c40ec4a47c4a72b80ba821f7213977?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
