This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car makes, revealing that higher-performance vehicles tend to have lower fuel efficiency. Each circle represents a car manufacturer, with its x-position indicating horsepower, y-position indicating torque, and size scaled proportionally to highway MPG using `d3.scaleLinear`. The color of each bubble, assigned via `d3.scaleOrdinal` with `d3.interpolateTurbo`, distinguishes between makes. Hovering over a bubble triggers a tooltip displaying the make name. The chart includes a legend for bubble size values and uses the `d3` framework with SVG rendering.
