{"version":"1.0","type":"rich","title":"Activity6_Q4.9","description":"This bubble chart visualizes the correlation between sepal length, petal length, and petal width across three iris species using the classic Iris dataset. Each circle's x-position maps to sepal length, y-position to petal length, and size to petal width, with color distinguishing species via `d3.scaleOrdinal` and the `d3.interpolateTurbo` color scheme. Hovering reveals a tooltip with the species name. The chart is rendered as an SVG using D3.js v7, with axes, labels, and legends for both size and color built through D3's scale APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b4af24417cd4c9eb9549e4de0a818b8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
