This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes horsepower and torque, while its size represents highway MPG, and its color distinguishes the manufacturer. The visualization uses d3.csv to load the data and d3.scaleLinear for axes and bubble scaling, with an SVG-based tooltip showing the car make on hover. A legend displays MPG value references and color-coded make labels.
