{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This animated bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across car makes using a CSV dataset. D3.js v7 renders SVG circles scaled by MPG and colored with a turbo-scaled ordinal palette. Interactive tooltips appear on mouseover, while the legend displays both bubble size reference circles and color-coded make labels. The implementation uses d3.csv, scaleLinear, scaleOrdinal, and event handlers for hover interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1618edf4523c469f80466123c0fb9042?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
