Animated Arcs
Four concentric animated arcs rotate continuously around a central point, each with a distinct color and its own random start and end angles. The arcs periodically change their sweep length and position, creating a dynamic, looping visual rhythm. Built with D3 v4, the example uses SVG paths and `d3.interval` to trigger transitions, while `transition.attrTween` and `d3.interpolate` smoothly animate each arc’s angles. The code generates random data for four arcs with varying radii and colors, drawing them with the `d3.arc` shape generator.
AI-generated descriptionThis little animation is used within the overview sneak-peek animation of the Stitch Fix Algorithms Tour. See Mike Bostock's heavily-commented Arc Tween example for an explanation of arc tweens in general. This animation is made only slightly more complex by the use of four arcs and by varying both the start and the end points.
