{"version":"1.0","type":"rich","title":"Activity_7.1","description":"This pie chart visualizes the distribution of total sales across product categories from an autosales CSV dataset, with each slice’s percentage and value in thousands shown in a side legend. The chart uses D3 v7’s `pie` and `arc` generators to compute and draw the segments, while `scaleOrdinal` assigns distinct colors. Data is loaded asynchronously via `d3.csv`, and sales strings are cleaned by removing dollar signs and commas before calculating totals and percentages.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d3a6e04336484ebe892ae1eeaf0d8a76?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
