{"version":"1.0","type":"rich","title":"Activity 6 Task 4 Q9","description":"This example loads the classic Iris dataset from a remote CSV file and renders a bubble chart using D3.js v7 with SVG. It plots sepal length on the x-axis and sepal width on the y-axis, while the size of each circle encodes petal length through a `d3.scaleSqrt`. The chart includes axes generated with `d3.axisBottom` and `d3.axisLeft`, along with custom axis labels. Circles are filled with semi-transparent steelblue and the code fetches data asynchronously via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2399ec4d0bb740a2870a1245d6a771ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
