This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car makes, using D3.js v7. Each circle’s position encodes horsepower and torque, while its radius scales with highway MPG, and color distinguishes the vehicle brand. The chart includes an interactive tooltip that reveals the make on hover, a legend for bubble sizing, and a color scale. The visualization is rendered as an SVG with smooth transitions, and the underlying data comes from a CSV file.
