{"version":"1.0","type":"rich","title":"Fork of Activity 7 Question 1","description":"This pie chart visualizes total sales by product category using a donut layout. It loads sales data from a remote CSV file via `d3.csv`, aggregates values with `d3.rollup`, and computes arc angles using `d3.pie`. Each slice is rendered as an SVG `path` with `d3.arc`, colored by `d3.scaleOrdinal` with `d3.schemeSet2`, and labeled at the arc centroid. A manual legend maps product names to their corresponding colors. The visualization demonstrates a standard D3 v5 pie chart workflow with external data loading and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f982b2a31bcb47dba6b79ad09c68f894?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
