{"version":"1.0","type":"rich","title":"question 4","description":"This bubble chart visualizes the Iris dataset, plotting petal length on the x-axis and petal width on the y-axis, with bubble radius proportional to sepal length multiplied by sepal width. Each of the three iris species is color-coded: skyblue for setosa, lightgreen for versicolor, and orange for virginica. The visualization uses D3.js v7 with the `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs to load the remote CSV data, map the values to scales, and render the SVG circles encodings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bc0bfbee22e241bca299833b6ec08e42?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
