{"version":"1.0","type":"rich","title":"Assignment 2.1.1","description":"This D3.js v5 pie chart visualizes the Air Quality Index by country, sourced from a CSV file hosted in a GitHub gist. The chart center displays the proportional slices, each colored via the ordinal category-10 color scheme, with a legend on the right listing country names and their corresponding Air Index values. The code uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate the slices and layout, and `d3.csv` to load and parse the data. A title, styled with a sans-serif font, appears at the top of the SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee602c791e804deda25603d6f027469f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
