{"version":"1.0","type":"rich","title":"Question 4","description":"This bubble chart visualizes the Iris dataset, plotting sepal length against sepal width, with bubble size and color representing petal length and species, respectively. It uses d3.v7’s `scaleLinear`, `scaleOrdinal`, and `axisBottom`/`axisLeft` to map data to position, radius, and categorical colors. Interactive tooltips appear on hover, showing species and sepal measurements. The SVG is rendered with D3’s selection and join operations, and a legend identifies the three species using a custom color scheme.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea5a86c39f8746678bc13a1159136427?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
