{"version":"1.0","type":"rich","title":"Activity6_bubblechart-TASK4(Question)","description":"This interactive bubble chart visualizes the Iris dataset, mapping sepal length and width to the x- and y-axes while encoding petal length as bubble radius. Each of the three species—setosa, versicolor, and virginica—is distinguished by color through a `d3.scaleOrdinal`, with a legend and tooltip revealing petal length on hover. Built with D3 v7, the visualization uses SVG circles, `d3.axisBottom` and `d3.axisLeft` for scales, and transitions for tooltip fade effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1627e692dd07487f8c2910ffb9556f02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
