This bubble chart displays the correlation between average horsepower, average torque, and highway MPG across car makes. Each circle’s position maps horsepower and torque, while its radius encodes highway MPG, and color distinguishes the manufacturer. The visualization uses D3 v7 to append SVG elements, scales, axes, and a tooltip that reveals the car make on hover. A legend explains the bubble-size scale for MPG values, and all data comes from a CSV file loaded asynchronously.
