{"version":"1.0","type":"rich","title":"question2","description":"This stacked bar chart visualizes the Iris dataset, showing the average measurements of sepal length, sepal width, petal length, and petal width for three Iris species: setosa, versicolor, and virginica. Using D3.js v7, the visualization applies `d3.stack()` to arrange the four numerical attributes as stacked segments within each species category. The code uses scale bands and linear scales for positioning, with color encoding via `d3.scaleOrdinal` and the Category10 color scheme. The resulting SVG provides a compact comparison of the relative contributions of each measurement type across species.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/41dff405f03741418f6345894a5df0c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
