This bubble chart explores the correlation between average horsepower, torque, and highway MPG across different car makes. Using the D3.js library (v7), circles are positioned by horsepower and torque on x- and y-axes, with radius and color encoding MPG and make respectively. The visualization includes an interactive tooltip that reveals the make on hover, implemented with mouseover, mousemove, and mouseleave events. A legend communicates both the MPG radius scale and color-coded makes, while data comes from a CSV file.
