A bubble chart visualizes the correlation between average torque, horsepower, and highway MPG for different car makes. Each circle's x-position corresponds to horsepower, y-position to torque, and radius scales with highway MPG, while color encodes the car brand. The visualization uses D3 v7 with an SVG rendering and includes interactive tooltips that display the car make on hover. A legend explains the bubble size scale for MPG values, and the color mapping uses a Turbo colormap.
