{"version":"1.0","type":"rich","title":"MK Pie Chart","description":"A dark-themed donut chart displays total sales by product category across 20 stores, with slices labeled by category name and percentage. Data from a CSV file is aggregated using `d3.rollups` and rendered with the reusable `pieChart()` function, which leverages `d3.pie` and `d3.arc` for the layout and `d3.scaleOrdinal` with `schemeTableau10` for coloring. Interactive tooltips appear on hover using `d3.select` and mouse events, while leader lines and a legend clarify slice values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f4e4a62764e14319bb3e2a2e9c6ab70f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
