{"version":"1.0","type":"rich","title":"Activity 6_Question 9","description":"This bubble chart visualizes the Iris dataset by mapping sepal length and sepal width to the x- and y-axes, while petal length controls the radius of each semi-transparent steelblue circle. It imports data via `d3.csv`, uses `d3.scaleLinear` and `d3.scaleSqrt` to encode variables, and renders axes with `d3.axisBottom` and `d3.axisLeft`. The chart demonstrates how bubble size adds a third quantitative dimension to a scatterplot.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8e01dfd92d1a4a4abeb572a7ffce1c4c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
