{"version":"1.0","type":"rich","title":"Activity 7_question1","description":"This example shows a donut chart of categorical sales data, with each slice labeled by category and a legend on the left. Hovering over a slice displays a tooltip with the percentage share of the total sales. The code uses D3 v7 with `d3.pie` and `d3.arc` to generate the pie geometry, and `d3.scaleOrdinal` with `schemeCategory10` for colors. Data is loaded as CSV from a GitHub gist, and the SVG is rendered with a centered group and a 200-pixel right margin for the legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee6236537a7b4e43b304d4f22afc6c1c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
