{"version":"1.0","type":"rich","title":"task8.4","description":"This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Rendered as SVG circles, each bubble’s x-position maps to horsepower, y-position to torque, and radius to highway MPG, with colors assigned per make via `d3.scaleOrdinal` and `d3.interpolateTurbo`. Hovering reveals a tooltip showing the car make. The chart includes axes, labels, a size legend for MPG values, and a color legend, all built with D3 v7 and data from `bubblechart.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/923e9fedf1b543848f37185716f2e967?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
