A bubble chart shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle's position reflects horsepower and torque, while its radius encodes highway MPG, and its color distinguishes the manufacturer. The visualization includes a tooltip that displays the car make on hover, a legend for MPG values, and a color-coded list of makes. Built with D3.js v7, the chart uses SVG, linear scales, and ordinal color scales to render the animated and interactive data.
