{"version":"1.0","type":"rich","title":"Area Chart Question 2","description":"This chart visualizes the distribution of operating system users for Android, iOS, and BlackBerry OS, aggregated from a CSV dataset spanning 2009–2023. Rendered as a pie chart using D3 v6, it displays percentage labels on each slice and includes a color-coded legend. The implementation uses d3.pie, d3.arc, and d3.scaleOrdinal for slice generation, coloring, and legend mapping, with data loaded via d3.csv from a GitHub gist. Styled with custom CSS, the SVG output emphasizes radial sectors and centered text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fbecb1a3479541679de49c775d41dfc7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
