{"version":"1.0","type":"rich","title":"Assigment2","description":"This example visualizes sales distribution by brand as an animated pie chart in SVG. It loads data from a CSV file via `d3.csv`, aggregates sales using `d3.rollup`, and renders slices with the `d3.arc` and `d3.pie` layouts. Hovering over a slice enlarges it via `d3.transition` and displays a bold label with the brand’s total sales. The chart includes a color-coded legend using `d3.scaleOrdinal` and a descriptive title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff77908721884b118a3de6b9ac022ada?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
