{"version":"1.0","type":"rich","title":"Question 1 of Activity 7.1","description":"This pie chart visualizes household expenditures by product category, with each slice labeled and connected to its corresponding value via an arrow line. The chart uses D3.js v7’s `d3.pie` and `d3.arc` generators to compute slice angles and paths, while `outerArc` and polylines position labels outside the circle. Data is loaded from a CSV file hosted on GitHub Gist. A legend, built with appended SVG rects and text, maps colors to categories, and `d3.scaleOrdinal` with `schemeCategory10` assigns categorical colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bca9c0247502425c98d097f8d353cb6e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
