This bubble chart explores the correlation between average torque, horsepower, and highway MPG across 31 car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while its radius scales with highway MPG and its color maps to the car make. A tooltip reveals the make name on hover. The visualization uses D3 v7 with SVG rendering, linear scales, and animation, pulling data from a remote CSV file. A legend displays MPG values (20, 40) as reference circles, and color swatches identify each make.
