{"version":"1.0","type":"rich","title":"Fork of task9","description":"This fork shows a pie chart of categorical quality values, with each slice colored and paired with a legend and axis labels for quality and frequency. It uses D3 v7’s `d3.rollup` to count data points per quality category from an inline array, then `d3.pie` and `d3.arc` to generate SVG paths. A `d3.scaleOrdinal` maps categories to two colors, and hand-built SVG rect and text elements form the legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f508b3c4983b44f4ae0e12cf1e8faa6f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
