{"version":"1.0","type":"rich","title":"Task 8 Tutorial 4 question","description":"This example demonstrates a packed bubble chart using D3 v4, visualizing a dataset of food items with their associated counts. The chart renders circles of varying sizes on a 600-pixel square SVG canvas, with each bubble representing an item and its area proportional to the count value. The implementation uses D3’s `d3.pack` layout, `d3.hierarchy` for tree building, and `d3.scaleOrdinal` with the `schemeCategory20` color palette to assign distinct colors. Each bubble includes a white label showing the item name and count, rendered with `d3.select` and SVG attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f592ff36dc144ccb94fa7f84c808882f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
