{"version":"1.0","type":"rich","title":"pie","description":"A guided breathing animation is presented as a segmented donut chart, with four colored arcs representing a cycle of inhale, hold, exhale, and hold phases. An animated gray overlay sweeps across the arcs to indicate the current phase, while a text label updates to show the active step. Built with D3 v6 and SVG, the code uses `d3.arc` to define arc shapes and `transition.attrTween` to animate the overlay’s angle. The duration of each phase is fixed, and the sequence repeats for a set number of cycles before stopping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7029344b20fa4cdf83e162d7ff1cef09?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
