Each circle’s x-position maps to horsepower, y-position to torque, and radius to highway MPG, while color encodes the car manufacturer using `d3.interpolateTurbo`. The chart features interactive tooltips on hover and includes a legend for bubble size and color. Data is loaded from a local CSV using `d3.csv`, with axes and scales built via `d3.scaleLinear` and `d3.axisBottom`/`d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3cb29783eb4c4ff09c9ad943984629a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
