{"version":"1.0","type":"rich","title":"Kvanto - pie v3","description":"This animated donut chart visualizes payment transaction counts by card method and status, sourced from a live API endpoint at kvanto.com. The chart groups data by order ID, filters to approved and declined statuses, and aggregates counts via `d3.rollup`. Using `d3.pie` and `d3.arc`, it renders colored slices with labels and polylines, applying `d3.scaleOrdinal` with an interpolated spectral palette. Transitions animate updates smoothly through `transition.attrTween` and opacity changes, while `d3.group` structures the hierarchical data before rendering in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e74b1f291b684e4ea718cd5ecf9e2016?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
