This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes, with each circle’s position encoding horsepower and torque, its radius encoding highway MPG, and its color representing make. The visualization uses D3 v7 with SVG rendering and interactive animations, including a tooltip that appears on mouseover to display the car make. The chart features a color legend for makes and a circle-size legend for MPG values, with axis labels and a title provided.
