{"version":"1.0","type":"rich","title":"question2.1","description":"This visualization shows a stacked bar chart of the Iris dataset, displaying the total sepal and petal measurements for each species. The chart uses d3.stack() to aggregate the four numerical attributes into color-coded segments per species, with a tooltip showing individual segment values on hover. The visualization renders with SVG, using d3.scaleOrdinal for colors, d3.scaleBand for the species axis, and d3.scaleLinear for the measurement axis. A legend identifies each attribute, and the data is loaded from an external CSV file using d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cdcd8359daee460c9d0018a9ef0725f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
