{"version":"1.0","type":"rich","title":"Task-9-10","description":"This visualization presents a pie chart that displays the distribution of items sold by country, with quantities aggregated per nation. The data is initially a flat list of entries, which is then grouped and summed using `d3.rollup` and `d3.sum`. The chart is rendered as an SVG using D3 v7, with slices created via `d3.pie` and drawn using `d3.arc`. Each slice is labeled with the country name and total quantity, and hover effects scale the slice via CSS transitions. The chart uses a categorical color scheme (`d3.scaleOrdinal`) to differentiate countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/666236a4943d4856a092efb2bcd1efac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
