{"version":"1.0","type":"rich","title":"Activity 7","description":"This pie chart displays total sales by product, using a CSV dataset loaded from GitHub. The D3.js v7 code (with d3.csv, d3.rollup, d3.sum, d3.pie, and d3.arc) aggregates the data and renders SVG slices labeled with product names. A color legend, built with d3.scaleOrdinal and d3.schemeCategory10, lists each product and its summed sales value. The chart uses white slice strokes and a centered layout within an 800x500 SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ede9631d98ae4d0187a024c4674d88b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
