{"version":"1.0","type":"rich","title":"Fork of Kvanto - pie v2","description":"This example shows an interactive pie chart visualizing transaction data grouped by card method (VISA, MASTERCARD, VISAELECTRON) and status, with data loaded from a remote API. The chart renders as SVG paths using `d3.pie` and `d3.arc`, with a donut layout and labels connected via polylines. The code uses `d3.rollup` and `d3.group` to aggregate transaction counts, and transitions animate arc updates and label repositioning via `transition.attr`. A spectral color scale maps categories, and clickable labels are appended for potential interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2607f7feeb184f4ea0b637eda6c5c035?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
