{"version":"1.0","type":"rich","title":"Pie Chart Question 1","description":"This pie chart visualizes the distribution of users across Android, iOS, and BlackBerry OS, aggregating yearly data from a CSV file into three slices with percentage labels. The code uses `d3.pie` and `d3.arc` to generate the SVG paths, `d3.scaleOrdinal` for color mapping, and `d3.csv` for data loading. Rounded corners on slices and a manual legend accompany the chart, while the title sits above the visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b0d0c25e3094f1e804dd9d67983f66f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
