{"version":"1.0","type":"rich","title":"Question 1 pie chart","description":"A pie chart visualizes the distribution of total sales across item categories, with values aggregated and labeled directly on each slice. The chart includes a legend and titles indicating the overall sales scope. It uses D3 v6 APIs including `d3.pie`, `d3.arc`, and `d3.rollups` to aggregate and render the data, with color encoding via `d3.scaleOrdinal`. The data is loaded as a CSV from a GitHub Gist, and the visualization is rendered as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a6cfe4364e7749a997bbcd08b1cc7a83?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
