{"version":"1.0","type":"rich","title":"Activity 6 Task 4 Q4","description":"This bubble chart visualizes the Iris dataset, showing sepal length on the x-axis, sepal width on the y-axis, and petal length encoded by circle radius. Circles are colored by species (setosa, versicolor, virginica), with a legend to the right. Hovering reveals a tooltip with species and measurement details. The visualization uses D3 v7 with SVG rendering, including `d3.scaleLinear` for axes, `d3.scaleSqrt` for radius mapping, and `d3.scaleOrdinal` for species colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b2b51d46ee8646b6b17ea4223f8dee5d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
