This bubble chart visualizes the relationship between horsepower, torque, and highway fuel efficiency for various car makes. Each bubble represents a car brand, with its position encoding horsepower and torque, while the bubble size corresponds to highway miles per gallon. The chart uses D3.js v7 and reads data from a CSV file, rendering bubbles via a force-directed simulation to manage overlaps and layout. The interaction allows users to explore the trade-offs between performance metrics and fuel economy across luxury and sports car manufacturers.
