{"version":"1.0","type":"rich","title":"Question4","description":"A bubble chart displays the Iris dataset, showing petal length through bubble size and species through color, with sepal length and width on the x and y axes. Hovering over a circle reveals a tooltip with species and petal length. The visualization uses D3.js v7 with SVG rendering, `d3.scaleLinear` and `d3.scaleOrdinal` for mapping, and animated transitions for the tooltip. A legend distinguishes the three Iris species, and the chart includes axis labels and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/baa3552c7f814bf99e2d3a20ddabd63c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
