{"version":"1.0","type":"rich","title":"PieChart for Activity 7.1","description":"This pie chart visualizes calories burned per 30 minutes across different exercises, using a dataset loaded via `d3.csv`. Each exercise occupies a slice with an extruded label and leader line, computed from start and end angles via the pie layout and `d3.arc` centroids. A color legend maps exercises to their corresponding slice colors. The chart is built with D3 v5, rendering arcs, labels, and leader lines as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/88c3fb1463264b88ba178bfe36ff8b6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
