Each circle’s x-position maps to horsepower, y-position to torque, and radius to MPG, with color distinguishing brands.

Built with D3 v7, it uses SVG, scales like `d3.scaleLinear` and `d3.scaleOrdinal`, `d3.csv` for data loading, and mouse events to show tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/29f8303ec359447185588958ab018255?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
