{"version":"1.0","type":"rich","title":" Activity 7_question1","description":"A pie chart displays categorical sales proportions, with each slice labeled and colored by category. Hovering over a slice reveals an HTML tooltip showing the percentage of total sales. The visualization is built with D3 version 7, using the `d3.pie()` layout and `d3.arc()` generator to create slice paths. It loads CSV data from a GitHub Gist via `d3.json()`, applies an ordinal color scale, and includes a custom legend. An SVG canvas renders all marks, while tooltip positioning tracks mouse coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/397eedaab2db4067a470d2ce55763fea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
