{"version":"1.0","type":"rich","title":"Assisgment 2 -question 1","description":"This example shows a pie chart of monthly sales totals, with each slice labeled by its month name directly on the chart. It loads CSV data from a GitHub Gist, aggregates the raw records by month using `d3.rollup` and `d3.sum`, then draws the chart with `d3.pie()` and `d3.arc()`. The SVG rendering uses `d3.scaleOrdinal` with `d3.schemeCategory10` for slice colors and places text labels at arc centroids.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e9588306ee224c10b48268bc229ec25e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
